Step 3—Conventional Trailer Weight Safety Report (Travel Trailer, Toad, Dinghy)

The premier self-service towing weight calculator providing the only 13 point safety report. Caution: This is not a pre-purchase calculator—use RV Tow Check .

If all your safety margins are displayed in GREEN , that's great! You have carefully paid attention to your vehicles’ load. Pat yourself on the back. Although this report is a good indicator of a safe load, Fifth Wheel St.'s vehicle and Conventional Trailer Weight Safety Report can never substitute for the advanced weighing procedure consisting of wheel by wheel weighing. Whenever possible, weigh each wheel position at a location that provides the advanced towing safety report. Visit the Wheel-by-Wheel Weighing Resources page to find a location near you.

If any of your safety margins are displayed in RED , then you are towing with a potential driving hazard. It's your responsibility to consider what you think is safe for your towing situation, whether it's 4 pounds overweight or 4000 pounds overweight. You need to take a careful look at how your vehicles are loaded. You may need to remove or relocate some items to better balance the load. In some instances, you may need to purchase a tow vehicle with higher towing capacity or purchase a trailer with less gross vehicle weight rating (GVWR).

Weigh-In Without WD System Activated

The only way to obtain the true and correct tongue weight from a truck scale is to weigh on the scale with the WD system deactivated. After weighing the tow vehicle and trailer with the WD system deactivated, enter the three scaled weights in items D , E and F .

Caution: Only disconnect the WD system near the scale location. It may be extremely unsafe to tow on the highway without the WD system activated.

Benefits of Weighing with Activated Weight Distribution System (For Trailers WD Systems)

A true and correct weight safety report weighs the vehicles in the same configuration as it is driven on the highway. It is unlikely, except for temporary mechanical failure, for one to tow their conventional trailer down the highway without the WD system activated. The benefits of weighing with the WD system activated and using this safety report are as followed:

Shows the weight of the front axle and the result will assist in determining if there is too much or too little weight distributed to the axle.

Shows the weight of the rear axle and the result will assist in determining if there is too much or too little weight distributed to the axle.

Shows the weight of the trailer axle(s) and the result will assist in determining if there is too much or too little weight distributed to the axle(s).

The results indicate wither the towing combination is safe or some ratings are exceeded or if there is an imbalance with the activated WD system in the normal towing condition.

Motorcoach Owners

The most common weight issue for motorcoaches is exceeding the vehicle's Gross Combined Weight Rating (GCWR). As for the tongue weight (TW) measurements, there is a little more flexibility in this area depending on the towing method. If you're towing a dinghy or toad with all four wheels on the ground (flat tow), expect very little TW. Even when towing a dinghy or toad on a dolly the TW will still remain fairly low but ensure you're not exceeding the rear Gross Axle Weight Rating (GAWR). Now if you're towing a conventional trailer, read the report the same as any other conventional towing combination.

Tongue Weight

Once you know the total loaded trailer weight, it is important to adjust the trailer load balance so that no less than 10% of the trailer's weight is on the hitch ball, and no more than 15%. SAE advises the optimum tongue weight be 10% because it reduces oversteer in the tow vehicle. If you discover that the trailer tends to sway at 10% tongue weight, increase the tongue weight incrementally until the sway stops. In some configurations, an anti-sway bar may be required. Foremost, follow any owner's manual instructions. Caution: Aways adjust tongue weight without weight distribution system activated.

The simplest onsite method to quickly measure the tongue weight is using the Weigh Safe ball mount shaft and ball.

How to Choose and Install the Right Weight Distribution System

Travel trailers offer an incredible sense of freedom and adventure, but they also require careful attention to safety and performance. One critical aspect of towing a travel trailer is ensuring proper weight distribution. In this guide, we’ll explore everything you need to know about choosing and installing the right weight distribution system for your travel trailer.

Table of Contents

Understanding the Importance of Weight Distribution Systems for Travel Trailer Safety

Weight distribution systems play a crucial role in travel trailer safety by evenly distributing the trailer’s tongue weight across the tow vehicle and trailer axles. This helps to:

• Improve steering and handling
• Enhance braking performance
• Minimize trailer sway
• Maintain even tire wear

Using a weight distribution hitch can significantly improve your towing experience and help prevent dangerous situations on the road.

Types of Weight Distribution Hitches: Trunnion Bars vs. Round Bars

Weight distribution hitches come in two main types: trunnion bars and round bars. Both types use spring bars to distribute weight, but they differ in design and functionality:

• Trunnion bars have a square profile and attach directly to the hitch head, offering greater ground clearance and increased weight capacity.
• Round bars have a round profile and attach to the hitch head using chains, providing a smoother ride and easier installation.

Consider your specific towing needs and preferences when choosing between trunnion bars and round bars.

How to Calculate the Required Weight Distribution Hitch Capacity for Your Travel Trailer

To determine the right weight distribution hitch capacity for your travel trailer, you’ll need to know the Gross Trailer Weight (GTW) and Tongue Weight (TW) . The GTW is the total weight of your loaded trailer, while the TW is the amount of weight pressing down on the hitch. As a general rule, the hitch capacity should be greater than the GTW and within the range of the TW.

Choosing the Right Weight Distribution Hitch Based on Your Travel Trailer’s Tongue Weight

Selecting a weight distribution hitch based on your trailer’s tongue weight is essential for optimal performance and safety. To find the right hitch, follow these steps:

• Determine your travel trailer’s tongue weight.
• Consult the hitch manufacturer’s guidelines for weight capacity.
• Choose a hitch that falls within the range of your trailer’s tongue weight.

Tips for Selecting a Weight Distribution System Compatible with Your Tow Vehicle

To ensure compatibility between your tow vehicle and weight distribution system, consider:

• Your tow vehicle’s towing capacity
• The receiver hitch size on your tow vehicle
• The hitch ball size required by your travel trailer
• The drop or rise needed to keep the travel trailer level

Always consult your tow vehicle’s owner’s manual and the hitch manufacturer’s recommendations to ensure compatibility.

The Benefits of Integrated Sway Control in Weight Distribution Systems

Integrated sway control can help to further minimize trailer sway and improve towing stability. There are two main types of sway control:

• Friction sway control uses friction to resist trailer sway, which can be adjusted to suit your towing needs.
• Dual-cam sway control uses cams to keep the trailer centered and reduce sway.

Consider a weight distribution system with integrated sway control for enhanced safety and performance.

How to Properly Measure Your Travel Trailer and Tow Vehicle for Weight Distribution Hitch Installation

Before installing a weight distribution hitch, measure your travel trailer and tow vehicle to ensure proper fit and adjustment. Key measurements include:

• Hitch ball height : Measure the distance from the ground to the top of the hitch ball on both the tow vehicle and travel trailer.
• Coupler height : Measure the distance from the ground to the bottom of the trailer coupler.
• **Drop or rise**: Determine the difference between the hitch ball height and the coupler height. This value will help you select the appropriate shank for your hitch.

Follow these steps to install a weight distribution hitch on your travel trailer:

• Park your tow vehicle and travel trailer on a level surface, and engage the parking brakes.
• Assemble the hitch head, shank, and hitch ball according to the manufacturer’s instructions.
• Attach the assembled hitch to your tow vehicle’s receiver and secure it with the appropriate hitch pin.
• Measure and adjust the hitch ball height to match the trailer coupler height.
• Connect the trailer coupler to the hitch ball and secure the coupler latch.
• Install the spring bars and brackets according to the hitch type (trunnion bars or round bars).
• Adjust the spring bar tension as per the manufacturer’s recommendations.
• Connect any additional sway control devices, if applicable.

Adjusting the Weight Distribution Hitch for Optimal Performance and Safety

Once your weight distribution hitch is installed, it’s essential to fine-tune the adjustments for optimal performance and safety. Key adjustments include:

• Spring bar tension : Adjust the tension to distribute the trailer’s tongue weight evenly across the tow vehicle and trailer axles.
• Sway control : If using a friction sway control device, adjust the friction to match your towing conditions.
• Hitch ball height : Recheck and adjust the hitch ball height as needed to ensure the travel trailer remains level.

The Role of Shank Length and Rise in Weight Distribution Hitch Selection

The shank length and rise play an essential role in ensuring proper hitch ball height and trailer leveling. The shank length determines the distance between the hitch head and the tow vehicle’s receiver, while the rise is the vertical distance required to match the hitch ball height to the trailer coupler height. Select a shank with the appropriate length and rise for your specific towing setup.

How to Choose and Install the Right Hitch Ball for Your Weight Distribution System

Choosing the right hitch ball is crucial for a secure connection between your travel trailer and tow vehicle. Consider the following when selecting a hitch ball:

• Ball size : Ensure the hitch ball size matches your trailer coupler.
• Shank diameter : Choose a hitch ball with a shank diameter compatible with your weight distribution hitch.
• Weight capacity : Select a hitch ball with a weight capacity greater than your trailer’s Gross Trailer Weight.

To install the hitch ball:

• Insert the hitch ball shank into the hitch head.
• Secure the hitch ball with a washer and nut, tightening it to the manufacturer’s torque specifications.
• Use a torque wrench to ensure proper tightening.

Troubleshooting Common Weight Distribution Hitch Issues and Solutions

Common weight distribution hitch issues include:

• Trailer sway : Check and adjust spring bar tension and sway control settings as needed.
• Uneven weight distribution : Reevaluate your travel trailer’s loading and adjust the spring bar tension.
• Hitch noise : Lubricate the hitch ball, spring bars, and other moving parts to minimize noise.

The Impact of Weight Distribution Systems on Tow Vehicle Handling and Stability

Properly installed weight distribution systems can significantly improve tow vehicle handling and stability by:

• Distributing weight evenly across the tow vehicle and trailer axles
• Reducing trailer sway
• Improving steering and braking performance

Always adjust your driving habits to account for the added weight and size of your travel trailer.

Proper Maintenance and Care for Your Weight Distribution Hitch System

Regular maintenance and care for your weight distribution hitch system will prolong its lifespan and ensure optimal performance. This includes:

• Inspecting the hitch components for wear
• Lubricating moving parts, such as the hitch ball, spring bars, and sway control devices
• Checking and tightening bolts and connections as needed
• Cleaning and protecting the hitch from corrosion and rust
• Storing the hitch in a dry and protected area when not in use

How to Safely Disconnect Your Weight Distribution Hitch When Not in Use

To safely disconnect your weight distribution hitch:

• Park your tow vehicle and travel trailer on a level surface and engage the parking brakes.
• Lower the trailer’s tongue jack to take the weight off the hitch ball.
• Release any tension on the spring bars, and remove them from the hitch head and brackets.
• Disconnect any sway control devices.
• Release the trailer coupler latch and raise the tongue jack to separate the trailer from the hitch ball.
• Remove the hitch from your tow vehicle’s receiver and store it properly.

Choosing Between Fixed and Adjustable Weight Distribution Systems

Fixed weight distribution systems have a set hitch head angle and shank drop/rise, while adjustable systems allow for customization to suit various towing setups. Adjustable systems offer greater flexibility, especially if you tow different trailers or change your tow vehicle, but they may be more expensive than fixed systems.

Upgrading Your Travel Trailer Suspension to Complement Your Weight Distribution Hitch

Upgrading your travel trailer suspension can enhance the performance of your weight distribution hitch and improve overall towing stability. Suspension upgrades include:

• Shock absorbers : Improve ride quality and reduce bouncing.
• Air springs : Enhance load leveling and support.
• Equalizer systems : Further distribute weight across the trailer axles.

Consult with a professional or your travel trailer manufacturer for recommendations on suspension upgrades.

The Role of Air Bags and Helper Springs in Improving Weight Distribution

Air bags and helper springs can be added to your tow vehicle’s suspension to enhance weight distribution, stability, and ride comfort. These components work by providing additional support to the tow vehicle’s suspension, helping to level the vehicle and maintain proper alignment when towing a heavy trailer.

Understanding the Limitations of Weight Distribution Systems and When Not to Use Them

Weight distribution systems have limitations and may not be suitable for all towing situations:

• Towing capacity : A weight distribution hitch does not increase your tow vehicle’s towing capacity.
• Surge brakes : Some travel trailers with surge brakes may not be compatible with certain weight distribution systems due to potential interference with the braking mechanism.
• Tow vehicle compatibility : Some vehicles, such as those with unibody construction or specific suspension types, may not be compatible with weight distribution hitches.

Always consult your tow vehicle’s owner’s manual and the hitch manufacturer’s guidelines to ensure the proper use of a weight distribution system.

Comparing Popular Weight Distribution Hitch Brands and Models

There are several popular weight distribution hitch brands and models on the market. When comparing options, consider factors such as:

• Weight capacity
• Hitch type (trunnion bars vs. round bars)
• Integrated sway control
• Ease of installation and adjustment
• Price and warranty

Some well-known weight distribution hitch brands include:

• Equal-i-zer

Take the time to research and compare different models to find the best weight distribution system for your travel trailer and towing needs.

DRIVING/TOWING - TOWING

These calculation tables are designed to make it easy to assess the effects of payload and towball weight when towing. Caravan and trailer weight distribution can also be calculated.

There are three main reasons for ensuring your solo vehicle or vehicle and trailer complies with the makers’ axle weight limits: safety, legal and insurance issues.

The safety implications of operating overloaded vehicles are obvious: more likelihood of braking, handling and tyre failure issues.

If you’re weighed at a roadside inspection station and found to be overloaded, you’re in trouble.  State and territory authorities have zero tolerance for any axle that’s overloaded, even if the vehicle or vehicle and trailer are within GVM and GCM limits: one overloaded axle is sufficient case for a hefty fine and a vehicle ‘grounding’.

In the case of vehicles towing heavy caravans that overloaded axle is always the rear drive axle.

Insurance companies have become much more vigilant about vehicle weights and may weigh a damaged towing vehicle and trailer before agreeing to process a claim. Many claims have been rejected on the grounds of illegal loading.

If you’re still reading that means you’re interested in towing safely and legally.

Before you progress to our distribution calculation tables can we suggest you read the following topics that are in our Towing section: Australia’s towing laws need to change ; ADRs and VSBs not enough to guarantee safe trailers and caravans ; Tow Ball weight and trailer stability ; Don’t believe 4WD makers’ towing ratings ; Electronic stability control ; Towing correctly and Safe and legal towing .

Yes, it’s a big read, but this is a life or death topic!

Calculating vehicle and trailer weight distribution

Until now, it’s been very difficult to ensure your vehicle and or trailer are legal, but our OTA calculation program allows quick guidance in this critical area.

The starting point is with actual weighbridge weights for your vehicle and trailer, and the unladen towball weight. The vehicle and the trailer need to be separated and weighed, with the trailer axles only – not the jockey wheel – on the weighbridge. Towball weight its best measured with a scale – around $80 at automotive outlets.

It’s best to start with a completely empty setup, but with a full fuel tank.

Then you need to find the maximum axle weights permitted by the vehicle maker(s) and/or tyre load ratings, and the maximum towball load allowed.

Next is to make sure you have correct dimensions for front and rear overhangs, and the wheelbase. Ditto for the trailer.

Using the ‘hamburger’ menu, you then enter the relevant weights and dimensions.

‘Playtime’ involves putting the weights of your vehicle and trailer payloads into the locations set out in the tables. When you move a weight to another location, the effect on axle weights is calculated automatically.

Our default vehicle is a 200 Series LandCruiser GXL, but you simply replace the sample values with those for your vehicle. If it’s a short-cab ute, not a wagon, the ‘back seat’ location is the forward end of the cargo tray.

Likewise, the trailer shown is a single-axle van, but, if you have a multi-axle van, put the axle weights for it into the table. Likewise if it’s a camper trailer: just enter the dimensions and weights.

We’ve split the payload areas into ‘zones’, but if you don’t have that many loading areas, just ignore the ones that don’t apply.

When measuring the trailer dimensions from the towball receiver to the load zone, measure to the mid-point of that zone. For example, if the loading area is a storage box on the chassis, measure from the towball receiver to the middle of the box.

In the case of ‘people payload’, measure from the front of the vehicle to the hip points of the front and rear seat rows and estimate the weight of passengers in those rows.

If the load area in a particular zone is large enough to embrace what might be two zones, just pick the mid-point dimension between the two zones.

When you’ve entered all the relevant weight and dimension data the axle and towball weight boxes automatically update with calculated totals. If the boxed figures remain ‘green’ that’s good, but if a box turns red the weight in that box exceeds the legal or manufacturer’s rating.

The calculator can’t include the weight transfer effect of using weight distribution bars, because their size and degree of tension are variables. However, the calculator shows coupled-up rear axle weight, allowing you to see if you need to transfer some of it.

Note that weight distribution bars don’t ‘remove’ ball weight, but transfer some of it to the tow vehicle’s front axle and the trailer axle(s). The calculator shows how much reserve weight capacity you have at the front axle and at the trailer axle(s).

Important point: if you wish to retain the figures you’ve input you’ll need to take a screen shot or print the page that’s on screen. Once you’ve clicked off the OTA webpage your input dimensions and weights will revert to the default ones.

Trailer Weight Distribution Calculator

Tongue Weight (lbs):

Trailer Weight (lbs):

How do you calculate weight distribution on a trailer? Weight distribution on a trailer is typically calculated by determining the tongue weight, which is the portion of the trailer’s weight that is supported by the hitch. Tongue weight can be measured using a specialized scale or by ensuring that the trailer is level and then measuring the weight on the hitch using a regular scale. The distribution of weight between the trailer’s axles can also be assessed by measuring the individual axle weights.

What percentage of weight should be distributed in a trailer? A general guideline is to aim for a tongue weight that falls between 10% to 15% of the total trailer weight. However, it’s important to consult the manufacturer’s recommendations for your specific trailer model, as optimal weight distribution can vary depending on design and intended use.

What is the proper weight distribution on a utility trailer? For a utility trailer, a common recommendation is to have approximately 60% of the weight distributed towards the front of the trailer and 40% towards the rear. This helps ensure proper stability and handling while towing.

How do I know what weight distribution hitch I need? To determine the appropriate weight distribution hitch, you need to consider the total trailer weight and the tongue weight. The weight distribution hitch should be rated to handle the tongue weight of your trailer. Consult the manufacturer’s specifications and guidelines for the weight distribution hitch to find the appropriate model based on your trailer’s weight.

Where should 60% of the weight in a trailer be distributed? If aiming for 60% of the weight towards the front of a trailer, this distribution refers to placing 60% of the total weight on the front half of the trailer, and the remaining 40% on the rear half. This helps maintain proper weight distribution for stability and control.

What percent of trailer weight should be on the tongue? As mentioned earlier, a general guideline is to aim for 10% to 15% of the total trailer weight on the tongue. This range provides a good balance of stability and control while towing. However, it’s important to consult the manufacturer’s recommendations for your specific trailer to ensure proper weight distribution.

How do you tell if a trailer is overloaded? Signs of an overloaded trailer can include difficulty in maintaining control, excessive swaying, reduced braking performance, and strain on the tow vehicle’s suspension or engine. Additionally, if the trailer’s tires appear to be under excessive load or if the trailer is sitting significantly lower at the rear end, it may indicate an overload condition. It’s important to be mindful of the trailer’s weight ratings and not exceed the manufacturer’s recommended limits.

How should weight be distributed on feet? When it comes to weight distribution on feet, it is generally advisable to distribute body weight evenly across both feet to maintain balance and stability. Placing too much weight on one foot can lead to instability and increase the risk of falls or injuries.

What happens if there is too much weight in the back of a trailer? Having too much weight concentrated at the back of a trailer can cause an imbalance and negatively affect stability and control. It can lead to an increased risk of trailer sway, difficulty in steering, and reduced traction and braking performance. It’s crucial to distribute the weight properly to maintain a balanced load.

What is the maximum trailer capacity for weight distributing? The maximum trailer capacity for weight distributing, often referred to as the weight distribution hitch rating or capacity, varies depending on the specific weight distribution hitch model. Different hitches have different weight ratings, so it is important to consult the manufacturer’s specifications to determine the maximum trailer weight that a particular weight distribution hitch can handle.

What is the max gross trailer weight distributing? The maximum gross trailer weight that can be handled by a weight distribution system depends on the specific weight distribution hitch model and its manufacturer’s specifications. Different weight distribution hitches have different weight ratings, so it is crucial to consult the manufacturer’s guidelines to determine the maximum gross trailer weight that can be safely distributed using a particular weight distribution system.

Where should the heaviest trailer be? The heaviest items or cargo on a trailer should typically be placed towards the front or over the trailer’s axle(s). This helps maintain proper weight distribution and reduces the risk of trailer sway or instability during towing.

Do I need a weight distribution hitch for a 6000 lb trailer? Whether a weight distribution hitch is necessary for a 6000 lb trailer depends on factors such as the trailer’s tongue weight and the tow vehicle’s specifications. As a general guideline, if the tongue weight approaches or exceeds 10% of the trailer’s total weight, it is recommended to use a weight distribution hitch for improved stability and control while towing. Consult the manufacturer’s recommendations for your specific trailer and tow vehicle to determine the appropriate setup.

Can you have too big of a weight distribution hitch? Using a weight distribution hitch that exceeds the necessary capacity for your trailer’s tongue weight can result in a stiffer ride and reduced suspension travel, potentially leading to a harsh towing experience. It is important to choose a weight distribution hitch that matches the trailer’s tongue weight within the appropriate range specified by the manufacturer.

Do I need a weight distribution hitch for a 4000 lb trailer? The need for a weight distribution hitch for a 4000 lb trailer depends on factors such as the trailer’s tongue weight and the tow vehicle’s specifications. If the tongue weight approaches or exceeds 10% of the trailer’s total weight, using a weight distribution hitch can help improve stability and control while towing. Consult the manufacturer’s recommendations for your specific trailer and tow vehicle to determine the appropriate setup.

Will too much tongue weight cause trailer sway? Excessive tongue weight can lead to instability and potential trailer sway. While some tongue weight is necessary for proper stability, having too much can overload the tow vehicle’s rear axle, causing the front of the vehicle to lift and reducing steering control. It is important to maintain an appropriate balance and not exceed the recommended tongue weight for your trailer.

How do I know if my trailer is balanced? To determine if a trailer is balanced, you can assess several factors. Ensure that the trailer sits level when connected to the tow vehicle, indicating that weight distribution is relatively even. Check that the tires are evenly loaded and not showing signs of excessive wear on one side. During towing, observe the trailer’s behavior for any signs of sway, difficulty in steering, or strain on the tow vehicle. If the trailer handles well and maintains stability, it is likely balanced properly.

Why does my empty trailer sway? Empty trailers can experience sway due to various factors, including wind resistance, improper weight distribution, or inadequate suspension settings. Without sufficient weight on the trailer’s tongue, the rear end can become light and prone to sway. Adjusting the weight distribution or using devices like sway control hitches can help reduce or eliminate sway.

Do you subtract tongue weight from trailer weight? No, you do not subtract the tongue weight from the trailer weight. The tongue weight is a portion of the trailer’s total weight that is supported by the hitch and the tow vehicle. When calculating the total weight of the trailer, the tongue weight is included in the overall weight measurement.

What can I tow with 3500 lb capacity? A tow vehicle with a 3500 lb towing capacity can typically handle trailers or loads weighing up to 3500 pounds, provided the weight distribution and tongue weight are within the manufacturer’s recommended limits. It’s important to consider the specific towing capacity of your vehicle, as well as any additional factors such as braking capabilities and trailer hitch ratings, to ensure safe and legal towing.

Does towing capacity include trailer weight? Yes, the towing capacity of a vehicle typically includes the weight of the trailer being towed. The towing capacity refers to the maximum combined weight of the vehicle and trailer that the vehicle can safely tow. It’s important to consider the weight of the trailer, as well as the tongue weight and weight distribution, when determining if a vehicle is suitable for towing a specific load.

How do you distribute weight on a 53-foot trailer? Distributing weight on a 53-foot trailer involves placing heavier items towards the front of the trailer and evenly distributing weight from front to back. Ideally, the load should be balanced to avoid excessive weight on either the front or rear axles. It may be necessary to adjust the placement of cargo or use load-distribution equipment to achieve proper weight distribution.

Why is my trailer so wobbly? Several factors can contribute to a wobbly trailer, including improper weight distribution, inadequate tongue weight, unbalanced cargo, worn suspension components, or issues with tires and wheel bearings. To address trailer wobbling, ensure proper weight distribution, check tire pressures and condition, inspect suspension components, and make any necessary adjustments or repairs.

What part of foot holds the most weight? The balls of the feet and the heel typically bear the most weight when standing or walking. These areas provide the primary support and balance for the body. However, weight distribution can vary depending on an individual’s posture, foot shape, and any existing foot conditions or injuries.

Do you weigh less if you stand on one foot? No, standing on one foot does not affect your actual body weight. However, it may create a sensation of reduced stability since the entire body weight is supported by a smaller surface area. Balance and weight distribution may be affected, but your overall body weight remains the same.

Which toes bear the most weight? The big toe (hallux) typically bears the most weight among the toes. It plays a crucial role in maintaining balance, propulsion during walking, and weight transfer during various activities.

Should you put the heavy stuff in the front or back of the trailer? For proper weight distribution, it is generally recommended to place heavier items towards the front of the trailer, closer to the tongue or over the trailer’s axles. This helps maintain stability, control, and proper tongue weight, reducing the risk of sway and improving towing performance.

What not to do when towing a trailer? When towing a trailer, it is important to avoid common mistakes such as exceeding weight limits, improper weight distribution, abrupt maneuvers, excessive speed, inadequate braking distance, and neglecting regular maintenance and safety checks. It is essential to follow proper towing procedures, adhere to legal requirements, and exercise caution while driving to ensure safe towing.

How much weight should be in the back of a trailer? The weight distribution on a trailer should not be excessively biased towards the rear. Typically, a balanced load with slightly more weight towards the front or over the axles is desirable. The specific weight distribution depends on the trailer type and design, as well as the manufacturer’s recommendations.

What can pull a 7000 pound trailer? A vehicle capable of safely towing a 7000 pound trailer will depend on factors such as the vehicle’s towing capacity, hitch rating, and appropriate weight distribution. Trucks, SUVs, or larger vehicles with adequate towing capabilities and proper equipment (hitch, brakes, etc.) are commonly used for towing trailers of this weight.

What’s the difference between weight carrying or weight distributing hitch? A weight carrying hitch (also known as a standard hitch) supports the trailer tongue weight directly on the tow vehicle’s hitch receiver, while a weight distributing hitch uses additional components (spring bars or chains) to redistribute a portion of the tongue weight to the tow vehicle’s front axle and trailer axles. Weight distributing hitches are typically used when the trailer’s tongue weight exceeds a certain threshold to improve stability and control.

What is the maximum weight for a 53-foot trailer? The maximum weight allowed for a 53-foot trailer can vary depending on local regulations and the specific weight limits imposed by transportation authorities. In the United States, for interstate travel, the federal weight limit is typically 80,000 pounds (including the weight of the trailer, cargo, and the truck). However, individual states may have different weight regulations, so it’s important to check the local requirements.

What is the maximum weight per axle? The maximum weight per axle can vary depending on local regulations and the specific weight limits imposed by transportation authorities. In the United States, the federal weight limit for a single axle on a commercial vehicle is typically 20,000 pounds (with some exceptions). However, state regulations may have different weight limits, so it’s important to check the local requirements.

What is mandatory if the gross trailer weight is 3500 or more? If the gross trailer weight (including the weight of the trailer and its contents) is 3500 pounds or more, it is usually mandatory to have electric brakes on the trailer in many jurisdictions. Electric brakes help improve braking performance and control when towing heavier loads.

What is the difference between GVW and GVWR? GVW stands for Gross Vehicle Weight, which refers to the total weight of a vehicle including its occupants, cargo, and fuel. GVWR stands for Gross Vehicle Weight Rating, which is the maximum weight that a vehicle is designed to carry, including its own weight and the weight of its payload (passengers and cargo).

How do I know if my trailer is too heavy for my truck? To determine if a trailer is too heavy for a truck, you need to consider the truck’s towing capacity and the trailer’s weight, tongue weight, and weight distribution. Compare the trailer’s weight (including its cargo) and tongue weight to the truck’s towing capacity and tongue weight limits specified by the manufacturer. It’s crucial not to exceed these limits to ensure safe towing.

What is the disadvantage of a weight distribution hitch? Some potential disadvantages of weight distribution hitches include added complexity and cost compared to standard hitches, increased setup time, and potential noise or clunking during towing. Additionally, weight distribution hitches may slightly reduce ground clearance and limit the articulation of off-road vehicles.

Can I use my weight distribution hitch without the bars? Weight distribution hitches require the use of spring bars or chains to distribute the tongue weight. It is not recommended to use a weight distribution hitch without the bars or chains, as the system will not function as intended and may compromise stability and control while towing.

Does weight distribution hitch reduce sway? Weight distribution hitches can help reduce sway by redistributing a portion of the trailer’s tongue weight to the front axle of the tow vehicle and the axles of the trailer. This improved weight distribution can enhance stability and control, reducing the likelihood of sway during towing.

What is the max tongue weight with distribution hitch? The maximum tongue weight that a weight distribution hitch can handle depends on the specific hitch model and its manufacturer’s specifications. Different weight distribution hitches have different tongue weight capacities. Consult the manufacturer’s guidelines for your particular weight distribution hitch to determine the maximum tongue weight it can safely accommodate.

How much weight does a weight distribution hitch take off? A weight distribution hitch helps distribute a portion of the tongue weight from the rear axle of the tow vehicle to the front axle of the tow vehicle and the axles of the trailer. The exact amount of weight transferred will depend on the specific weight distribution hitch and its design. It is important to refer to the manufacturer’s specifications for the weight distribution hitch you are using.

Does a 5000 pound trailer need a weight distribution hitch? Whether a 5000 pound trailer requires a weight distribution hitch depends on factors such as the trailer’s tongue weight and the tow vehicle’s specifications. If the tongue weight approaches or exceeds 10% of the trailer’s total weight, it is generally recommended to use a weight distribution hitch for improved stability and control while towing. Consult the manufacturer’s recommendations for your specific trailer and tow vehicle to determine the appropriate setup.

What is the ideal trailer weight distribution? The ideal trailer weight distribution depends on various factors, including the trailer’s design, axle configuration, and the manufacturer’s recommendations. As a general guideline, it is desirable to have a balanced load with slightly more weight towards the front or over the axles, while avoiding excessive weight on the rear end.

Do you need a weight distribution hitch for a 3500 lb camper? The need for a weight distribution hitch for a 3500 lb camper depends on factors such as the camper’s tongue weight and the tow vehicle’s specifications. If the tongue weight approaches or exceeds 10% of the camper’s total weight, using a weight distribution hitch can help improve stability and control while towing. Consult the manufacturer’s recommendations for your specific camper and tow vehicle to determine the appropriate setup.

What does too much tongue weight look like? Excessive tongue weight can cause the front of the tow vehicle to sag or appear lower than normal. This may result in reduced clearance between the rear bumper and the road, improper headlight alignment, or reduced steering control. Additionally, the rear suspension of the tow vehicle may become compressed, affecting ride quality and handling.

What does too much tongue weight feel like? Excessive tongue weight can lead to a heavy and unresponsive feeling in the steering of the tow vehicle. It may cause the rear end of the tow vehicle to feel unsettled or sag, negatively impacting stability and control. Excessive tongue weight can also strain the tow vehicle’s suspension, potentially affecting braking performance and overall towing experience.

What happens if weight distribution hitch is too high? If a weight distribution hitch is set too high, it can result in inadequate weight transfer to the front axle of the tow vehicle. This can lead to reduced steering control, compromised braking performance, and increased stress on the rear axle of the tow vehicle. It is crucial to properly set up the weight distribution hitch according to the manufacturer’s instructions to ensure optimal weight distribution.

Should your trailer be level when towing? Ideally, your trailer should be level when towing to ensure proper weight distribution and stability. A level trailer helps distribute the load evenly on all axles, reducing the risk of sway and improving handling characteristics. However, it’s important to consult the manufacturer’s recommendations for your specific trailer to determine the optimal towing setup.

What percent of trailer weight should be on the tongue? A general guideline is to aim for 10% to 15% of the total trailer weight on the tongue. This range provides a good balance of stability and control while towing. However, it’s important to consult the manufacturer’s recommendations for your specific trailer to ensure proper weight distribution.

Why don’t people balance trailer tires? Trailer tires should be balanced to minimize vibration and ensure even tire wear. However, some people may overlook balancing trailer tires, assuming that trailers don’t require the same level of balancing as passenger vehicles. Neglecting to balance trailer tires can lead to uneven wear, reduced tire lifespan, and potentially affect trailer stability during towing.

Why does my trailer still sway with a weight distribution hitch? While a weight distribution hitch can help reduce sway, it may not completely eliminate it in all situations. Factors such as wind conditions, improper weight distribution, trailer design, and driving speed can still contribute to sway. It is important to ensure proper setup, including correct weight distribution and adjustment of the weight distribution hitch, to minimize sway.

Does hitch height affect trailer sway? The hitch height can affect trailer sway to some extent. An incorrect hitch height, either too high or too low, can lead to improper weight distribution and negatively impact towing stability. It’s important to set the hitch height according to the manufacturer’s recommendations for your specific trailer and tow vehicle.

At what speed does trailer sway start? Trailer sway can begin at various speeds depending on several factors, including trailer design, weight distribution, road conditions, wind speed, and driving habits. In some cases, even lower speeds can trigger trailer sway, particularly if the setup is not properly balanced or if external factors exacerbate the situation. It is crucial to maintain appropriate speeds and drive attentively to prevent or mitigate trailer sway.

Where Is The Weight In Your Trailer?

What’s the big deal with Weight in my Trailer?  Isn’t Weight just Weight?  Yes, I know about tongue weight, but the trailer is made to carry weight.  So, if I am below the specified weight ratings, what does it matter?  If you have ever felt this way, you are right – mostly.

Of course, the mass we call weight is just that, and trailers are made to carry it.  However, the location of the weight with respect to other parts of the trailer also matters.  It matters in the design, and also in the practical setup for a comfortable, stable towing experience.  Most of all, it matters with loading the trailer for a stable ride.

Starting With Design

One of the most important decisions when designing or building a trailer – Where Does The Axle Go?   We set the axle position so that the tongue weight is appropriate.  That is a HUGE contributor to trailer stability.

We know if the mass on the trailer is too far forward , the tongue weight will be too high.  High tongue weight puts more weight on the hitch, and extra stress in the trailer tongue.  – Both of these conditions are OK if both the tow vehicle and the trailer frame can handle it.

On the other hand, if weight in the trailer is too far back , the trailer will be very unstable.  Things like sway and fish-tailing are frequent descriptors of this kind of instability.  Here is a video of a trailer having some of this instability.  Both trailer weight and where it is on the trailer definitely come into play with this kind of instability, for sure.

With most calculations for Axle Position and Tongue Weight, the distribution of weight does not come into play.  We look at the total weight and the total center of gravity (a little in front of the axles).  For example, follow the calculations in both of these articles:  “ Trailer Build:  Where Does The Axle Go ”  and  “ Calculating Axle Position “.  These show 2 methods for setting the axle position based on where you start – from scratch, or from an existing trailer.  Yet, these are Static calculations, so they do not consider dispersion of the load.

The static calculations are certainly good, but today, in this article, we will go one step farther in understanding where and how placement of the weight in the trailer matters.

Location Of Trailer Load

In practice, it is not just the weight of the trailer, or even where the center of mass is for the trailer.  When towing, the dynamics also include distribution of weight around the trailer.  Here are 3 images illustrating what I mean.

Image 1 :  Evenly Distributed Weight on the Trailer.

When doing calculations, we often think about the trailer weight as evenly distributed over the bed.  In practice, that is not usually true.

Image 2 :  Weight Front and Back on the Trailer.

This 2nd image has the same amount of weight as in Image 1, so both the tongue weight and axle weights are the same.  Calculation results for tongue weight and axle position are exactly the same.  However, as you can see, the distribution of trailer weight is totally different.  Does that matter?

Image 3 :  Weight at Center-ish of Trailer.

Our 3rd example has weight focused near the trailer deck center.  Like the 2 above, the tongue weight, axle weight, and calculation results for axle position are the same.  Again, this is just a change in where the load is physically located.  The center of mass for all 3 is the same (horizontally).

Now the question.  Does any of this matter?  And, Why?  or Why not?

Trailer Weight For Towing Experience

I was always taught to put the heavy things toward the front of the trailer, then lighter things toward the rear.  While that is not bad advice, a better approach is available.

Look at a top view of a trailer like these 2 images.  If you try to “twist” the trailer as with the arrows, which one is easier to move?  More important, once it starts to twist, for which trailer is it easier to stop the motion?

This is the physics concept of rotational moment of inertia .  We intuitively know if the weights are at the ends of the trailer deck, it is harder to twist back and forth.  So if we have a load which is more central, it has far less rotational moment of inertia.

When we are driving, there are forces that make the trailer want to twist like this — wind, road undulations, and driving inputs.  We can’t get rid of the forces that cause these minor rotational movements, so we need to make it easy for the trailer to “settle back” after inputs happen.  More rotational inertia (like the blue weights) makes the trailer harder to “settle” after such inputs.

What does this mean?

Here are several important implications for distribution of weight on the trailer.  (Please note, we are not talking about Weight Distribution Hitches, those are loosely related, but not part of this article.)

• Focusing weight toward the center of the trailer decreases the rotational inertia about the vertical axis, and the trailer becomes more stable.  While moving the load to the trailer center is not always possible, we certainly do not want to put the heavy bits near the ends.
• Heavy bits near the front are less intrusive for stability than at the rear.  The hitch at the tow vehicle acts as a secondary pivot, which gives more control for weights at the front.  However, we do not want to overdo it for tongue weight.  See more below.
• Even distribution of load usually works just fine.  Don’t get to worried about the distribution of weight, but do be conscious of it.
• Lower center of mass is also better.  The images above simplify the truth of dynamics, because there are forces, like wind and cornering, that want to tip the trailer, which is another order of complication.  As we think about dynamics, height is worth mentioning.  While this is a lower priority effect, it is important just the same.  More care in corners, and slower speeds are recommended for trailers with a high center of mass.
• Finally, keeping the weights generally centered left to right.  Yes, it stands to reason, but we mention it here for completeness.

How much does any of this matter?

Let’s shift gears a little and look more at a few details.  Don’t worry, we will come back to the practical applications.

What Is Trailer Weight?

It is easy to make the argument that axles, wheels and tires are unsprung weight and therefore not included in calculations with trailer weight.

Another one that is similar . . . Is tongue weight really part of the Trailer Weight when we are figuring out how much load the axles carry?  After all, if the tongue has 10% of the trailer weight, then we could actually have an 11,000 lb trailer on 10,000 lbs axles.  Right?

These are both easy arguments to make when thinking about a trailer.  While I do not have a definitive answer about when it is right or wrong to consider unsprung and total weight or to know exactly what an axle will carry, I guarantee you if you push the limits you will have problems.

I always recommend using the trailer weight total, as measured on a scale.  So, the total trailer weight includes the axles, wheels, and the tongue weight.  If 10% of the trailer weight is on the tongue, and a hundred or so pounds are are in the wheels (unsprung weight), that gives you a small margin for safety at the axles.  Why push it?  Why tempt disaster?

Does it matter how many axles the trailer has?  Read this other article to see how single or tandem axles relate .

Then there is a third bit that enters in.  What is actually the best tongue weight percentage?

Calculations for Tongue Weight

All of the above arguments hinge on subjective and empirical observations about tongue weight and stability.  The 10% to 15% tongue weight numbers we talk about come from observations that tend to work almost all the time.  It is a “Rule of Thumb”, as a recommendation.  If you want to get into super nitty gritty detail, there is always plenty of room to calculate possibilities.

On the other hand, mother nature does not follow exactly our calculations anyway, because we do not consider all the various possibilities of conditions.  That is why the rules of thumb exist.  If you think about it, the difference between 10% tongue weight and 15% tongue weight is actually quite large.  If you target 12% tongue weight and leave a little hand waving space, you will be right most of the time.

I guess what I am saying:  Don’t get too wrapped up in the exact numbers because the true numbers change with many factors (wind, wind direction, pitch, yaw, bumps, other passing vehicles, road crown, loading unevenness, dynamics, etc.).  There is all too much in the variations to even think about.

The truth is, regardless of all the changing variables, the trailer needs to be stable.  So, we get there by observing the millions of trailers that have gone before.  Some have stability issues, some cause horrific accidents.  Yet, some always pull perfect and stable.  We know what generally works and what does not, so we create rules of thumb as guides.  Yes, every trailer is different, so we need to take that into consideration, especially in the design process.  That is where experience comes in.

Side Note on Tongue Weight

I had one European reader tell me I was promoting tongue weights that are much too high.  He claimed it is unnecessary.  He said small tow vehicles do not need as much tongue weight.  I mention this to dispel a myth.  What he is saying is opposite the physics.

All the science says stability is best when the tow vehicle significantly outweighs the trailer.  Then, you can get away with a little lower tongue weight – into the 7% or 8% range.

Another trick that works – if the load on the trailer is concentrated near the axle then a really long tongue allows a lower tongue weight.  So if the tongue weight would be 10% with a normal tongue, if you make the tongue really long, the actual tongue weight is lower because you are using a longer lever.  (Please note there are other considerations too, for a long tongue , both positive and negative.)

Finally, you can get away with very low tongue weights if you drive really slow.  At speeds below 20 Kph, the dynamic energy is just not enough to create instability.  Driving super slow is not an option in most roadway situations, but for completeness, it is worth mentioning.  The opposite is also true:  Higher speed, puts more energy in the system, so it is more susceptible to trouble.

A trailer that seems stable at moderate speed can become a huge problem at higher speeds.  We see this in serious trailer sway accidents.  Someone pulling the RV just fine for many miles, accelerates to pass, then the wind disturbance of passing excites the trailer uncontrollably, and a horrible accident happens.  Distribution of weight in the trailer is almost always a big factor.

Where To Put Weight In The Trailer

Theory is good and all, but how about a practical approach?  OK, here are Practical Recommendations with a list in order of importance.

• Make sure all weights are within the tow vehicle specifications .  That is GVAR (axles), tongue weight, trailer weight, and total system.  This includes all the people and things in the tow vehicle also.  If you are not sure, measure them.  (Believe me, the hassle of getting weights is a whole lot less than picking up pieces after an accident.)
• Adhere to the recommended weights for the tongue and axles.  Total weight of the trailer less than GTWR, tongue weight in the 12% range (between 10% – 15%).
• As much as practical, focus weight toward the center of the trailer – see the images above.  For many trailers, like an RV, it is not really practical to do completely, but do not put extras at the ends of the trailer.  For instance, don’t hang a generator or a storage box on the back.
• Keep center of mass as low as practical.  Again, this is not always easy or even possible, so do what you can, and do not make it obnoxious.  Like, don’t put a generator on the roof of a tall RV.  If you have a high center of mass, slow down.
• Please note the above recommendations are more important as the trailer gets longer, if it has a lot of side surface area, as it gets taller, and as it gets heavier.  (In that order of importance.)
• If the trailer weighs significantly LESS than the tow vehicle, these weight issues are less important.
• Finally, if the trailer EVER acts squirrely, stop and figure it out.  Redistribute the weight if needed.  Check tires for low pressure.  Check springs for breakage.  If that is not practical, slow down.  Speed increases system energy, and if it starts to get unstable, it is much more difficult to bring it back into control.

Have a Wonderful Trip

I believe every accident from instability has some warning signs, often long before the crash.  It is a matter of seeing, or feeling them, then acknowledging what it is.  An ostrich with his head in the sand is much more likely to be eaten than the ostrich running with his head high and his eyes wide open.  For you own safety, please do not ignore even the earliest hints of instability.

Common Methods for Measuring Tongue Weight

1. Metal Scale:

A metal scale is a traditional, simple and relatively inexpensive tool for measuring tongue weight.

This device is usually made of steel and placed beneath the tongue of a travel trailer. The weight of the tongue is determined by the weight sensed on the scale.

This is an easy method, but accuracy may be an issue if the scale isn’t properly calibrated.

2. Tongue Weight Gauge:

This is a more advanced and accurate tool for measuring the tongue weight of a trailer.

It is basically a gauge, often digital, that is placed under the tongue of the trailer and measures the weight through pressure.

It is much more accurate than the metal scale and is highly recommended for trailers or campers that require precise measurements for safety reasons.

3. Tongue Scale:

A tongue weight scale is commonly available at trailer towing supply shops, and it’s a small scale particularly designed for measuring the tongue weight of the trailer.

It’s extremely straightforward to calculate the weight of the tongue using the tongue weight scale. 

It involves only two steps, including placing the scale under the trailer jack and taking the reading.

If the jack doesn’t fit properly, you can place a sturdy pipe vertically between the scale and the coupler.

For better convenience, you can buy a model like the CURT BetterWeigh towing scale.

You can sync this device with your smartphone and get real-time towing weights as well as gross combined weight and weight distribution.

4. Weighing Platform:

Weighing platforms are devices that allow you to weigh the tongue of your trailer.

They are accurate and easy to use, requiring only that you place the platform on a level surface.

It will measure the tongue weight and also provide a reading of the trailer’s total weight.

This is a great tool for those who need to measure tongue vehicle weight often.

5 Calculating with a Bathroom Scale

You can also measure the tongue using a normal bathroom scale instead of a tongue weight scale.

However, the bathroom scale has limitations, like it might not measure over 300 pounds. 

In addition, you have to put plywood on it before placing the tongue to protect the scale’s finish.

If you expect the tongue weight to be less than 300 pounds, put it on the scale.

If the tongue vehicle weight is likely to be more than 300 pounds, you can set up a test using some pipes and boards. Below is the step-by-step process:

• Park your trailer on level ground and chock the wheels.
• Place a 2×4 or a sturdy board below the trailer tongue on the ground. Make sure the board is a minimum of 3-1/2 feet long.
• Place your bathroom scale around two feet away from the trailer tongue and position a block roughly 1 foot away from the trailer tongue. As mentioned, place plywood on top of the bathroom scale to protect its finish.
• Put one horizontal pipe in the middle of the bathroom scale and the other in the middle of the block. Then note the distance from the tongue. Keep the pipe two feet away from the middle of the trailer tongue and one foot away from the block.
• Place a pipe vertically underneath the tongue and keep lowering the jack until the coupler rests on the pipe completely.
• Finally, note the bathroom scale and multiply the number by 3, which will be your desired tongue weight.

Calculating with a Vehicle Scale

Another alternative method to calculate tongue weight is by using a vehicle scale at the local dump. The process is:

• Weight the vehicle without the trailer hooked up.
• Weight the vehicle once again, hooking up the trailer. Make sure the trailer wheel doesn’t touch the scale.
• Then deduct the reading without the trailer from the reading with the trailer and the difference is your required tongue weight.

Proper Tongue Weight

Maintaining proper tongue weight is crucial. Too little torque weight can cause the vehicle to sway from side to side and makes it difficult to keep control behind the wheel.

Conversely, excessive vehicle tongue weight can weigh down the rear wheels of the vehicle and make steering fairly difficult.

Typically, the tongue weight should be around 10% to 15% of the loaded trailer’s total weight. It is also known as GTW (gross trailer weight).

It means if you are hauling a trailer with around 2000 pounds of cargo, the tongue weight should be around 400 to 600 pounds.

Why Tongue Weight Calculator Is Important

1. helps ensure proper balance and stability.

Utilizing a tongue weight calculator helps maintain balance between the trailer and the towing vehicle, ensuring that the tongue weight is properly distributed and the vehicle is not overloaded.

2. Encourages safe and comfortable trailering

Tongue weight is a major factor to consider when determining safe towing capacity. A calculator helps you determine the ideal tongue weight for your trailer and towing vehicle combination.

3. Prevents vehicle overload

Ensuring that the tongue weight is correctly proportioned will prevent overloading the vehicle, which can cause instability or create a dangerous situation.

4. Helps you determine the ideal towing vehicle

Using a tongue calculator is a valuable tool to use when selecting a towing vehicle. It can help you make sure the vehicle you choose is suitable for your application and make sure you don’t overload it.

5. Reduces the risk of accidents and damage

An overloaded vehicle is more likely to be involved in an accident, which could result in costly damage to the trailer or vehicle, or even injury to the driver or occupants.

The vehicle tongue weight calculator helps ensure that the trailer and vehicle are appropriately matched and safely loaded.

6. Improves trailer handling

Finding the right tongue weight for your trailer and vehicle combination will help maintain an even distribution of weight over the towing hitch, improving overall handling and braking.

7. Maximizes fuel efficiency

When everything is properly balanced and evenly distributed, the vehicle is able to use its power more efficiently, reducing fuel consumption and maximizing fuel efficiency.

8. Maintains proper torque

Proper vehicle tongue weight helps ensure proper torque between the trailer and the towing vehicle, avoiding undue stress on the suspension and axle that could damage the trailer or vehicle.

9. Promotes a longer lifespan

Overloading your vehicle or trailer can damage critical components and reduce the lifespan of your equipment.

Using a tongue calculator helps ensure that these components aren’t placed under excess strain and maximize their service life.

10. Promotes smooth, safe trips

The right combination of tongue weight and trailer weight distribution makes for a smoother and more comfortable towing experience, and a safer trip overall.

How To Maintain Proper Tongue Weight

In general, every towing vehicle comes with information about the safe towing weight.

A vehicle owner shouldn’t tow more than the recommended handle that it can’t handle. 

If you load over or under the gross trailer tongue weight, you should adjust the load before starting the vehicle.

If the tongue weight is too low, move some cargo near the front of the trailer to add more tongue weight. 

Conversely, if the weight is too much, move the cargo away from the tongue. You may also need to remove cargo to avoid damaging the tow vehicle.

While adjusting the cargo from front to back, try to maintain the balance on the right and left sides. 

Why Is Maintaining Proper Tongue Weight Vital for Towing? 

Calculating and maintaining proper tong weight is crucial to avoid causing a driving hazard to the driver himself as well as others on the road.

Incorrect tongue weight can easily cause trailer sway, which makes it difficult to regain control, making it extremely dangerous.

Other potential consequences of incorrect tongue weight include:

• Tire blowouts.
• Brakes that become unresponsive.
• Traffic accidents.
• Serious damage to the trailer or vehicle.
• Rear tire overload.
• Personal injury or even death.

Is The Tongue Weight And The Hitch Weight The Same?

No, the tongue weight and the hitch weight are not the same.

Tongue weight is the weight that the trailer places on the hitch of the tow vehicle, while the hitch weight is the weight of the trailer that is transferred to the hitch and onto the tow vehicle’s axles.

The tongue weight should be a portion of the total weight of the trailer and its contents and is an important factor in determining the safe towing capacity of a vehicle.

The hitch weight, on the other hand, is the weight that is actually transferred to the hitch and onto the tow vehicle’s axles and is used to determine the stability of the towing combination.

Is The Higher Or Lower Trailer Tongue Better?

Neither a higher nor a lower trailer tongue is better. Maintaining a balanced tongue weight is always best. But if you can’t maintain the balance, go slightly lower.

Can Too Much Tongue Weight Cause Sway?

Yes, too much tongue weight can cause swaying from side to side and make it challenging to control. Even the extra force can overload the rear tires of the vehicle and push the back end of the towing vehicle around.

Final thoughts

The Tongue Weight Calculator is a great tool for helping people accurately and quickly calculate their tow vehicle’s load capacity.

It’s simple to use and provides immediate results, making it a great resource for anyone who needs help figuring out the right amount of weight their vehicle can safely handle.

Overall, the Tongue Weight Calculator is an invaluable tool for anyone looking to safely and accurately plan their trips.

How to Weigh a Travel Trailer

I’m rather enjoying these “how to” types of write-ups. I need to do more writing about my actual camping experiences, but I’ll get there eventually. As I’ve written before, I’m a huge advocate of getting your rig weighed for peace of mind knowing that you’re within ratings and for a fantastic educational experience.

Here’s the actual process that you should go through with getting weighed when pulling a travel trailer. I don’t get into digesting the numbers, but there are plenty of forums where you can post, “Hey I weighed, and this is what I got” that will help you out.

Assuming that you’re doing it at a CAT scale that has 3 scales that you pull onto:

• Weighing Truck and Travel Trailer with weight distributing hitch (WDH) hooked up; you want your truck’s front tires (aka steer axle) on the first pad; truck’s rear tires (aka drive axle) on the second pad; all trailer axles on third pad (see the graphic above)
• Weighing Truck and Travel Trailer without weight distributing hitch hooked up; put the WDH bars into the bed of the truck
• Weighing Truck Only; park the travel trailer in a truck parking spot, put the WDH bars with the travel trailer (locked inside) and come back around to just weigh the truck

You’ll want to pull off of the scale between weightings #1 and #2 to remove the WDH bars and whatnot. It’ll keep you from holding up the line and confusing the scale master.

Important Notes for Weighing

Throughout all 3 weighs, nothing should change – no moving of passengers, no one goes to the bathroom, etc. Do them all at once (not before and after a trip, for instance).

As well to get as realistic numbers as possible, you want to be packed like you were ready to go camping on your average trip (weekend, week, month – whatever is normal for you). If you don’t have all of your passengers, you’ll have to add their weight when you evaluate your results.

Other Scales

Now, if you’re using a different scale (quarry, dump, etc.), they likely only have a single scale that you pull onto. You essentially want all of the same weights of each axle, so you’ll just have to move the truck more often to get individual weights (pull up with just the front tires, then the front and rear tires, then front, rear and trailer tires). And, it’ll require more math to figure out each axle’s weight.

A Tip for Cat Scales

If you’re going to a CAT scale, it can be a challenge to reach the call button. I found I had to stretch, but I could reach it (just not hear real well). Many people are taking a short 3′ stick of some sort to push it *or* going inside ahead of time to get the phone number of the weigh desk and calling that instead of using the button.

What is the Cost?

My CAT scale weightings costed me $10 for the first weigh and then $1 or $2 for each re-weigh. I’m not sure what the other kinds of scales cost – my guess is free to about the same.

What Can I Tow Calculators

Towing pin/tongue weight calculator, 20 comments.

You fail to mention the normally observed axle to axle variation or the side to side variation seen on almost all RV applications. While this variation may be as little as 50 Lbs it is not unusual for this unbalance to be enough to push a tine into the next level of minimum inflation. In some extreme cases the imbalance has been as much as 500 to 1,000 lbs.

I would like to ask if you know where a person can purchase the mobile weigh scales that slide under each trailer wheel. We live in Lethbridge, Alberta Canada and all we have are platform weigh scales and this would only give me the total weight of the trailer but not the individual weight on each tire. Our trailer is a Jayco 19RD with tandem axles. Please send me an email address or company name who makes the portable weigh scales. Thanks

No idea, but I believe they’re not cheap- something in the order of thousands of dollars for a set.

I took my travel trailer to the CAT scales and followed your instructions. Now how do I figure actual tongue, axle and total weight.

Randy, you can use my other site – towingplanner.com that has a calculator that will calculate it all out for you.

I did not know how to calculate tongue weight. Thanks.

I did know how to calculate tongue weight. Thanks

I live in illinois and i just started RVing this summer. My trailer is pretty set on things added and would like to weigh it to see where i am…could you help me with info on where i could take it to be weighed? I live in Naperville Ill. Thanks!

Sure! It looks like there is a truck stop called Greater Chicago I-55 that has a scale. Here it is on a map .

What is the weight actually used for?

When weighing just the truck (3rd step), do you leave the weight distribution hitch on the truck or put it and the bars in the trailer?

Doesn’t entirely matter. I usually say to throw them into the truck bed.

I have the same question, but not sure I understood your response. On the third step when you are weighing only the truck you say to leave the WDH bars with the trailer. Should we remove the hitch from the receiver on the truck and leave that with the bars in the trailer?

Thank you for putting together such great resources!

I see, I must have skimmed the last comment and read the question wrong. I would leave the WDH on the truck because you don’t want it’s weight added to the trailer’s tongue weight.

Thank you very much! I have a follow up question if you don’t mind.

Due to conditions when I visited the CAT scale, I wasn’t able to fill up the tank or weigh the truck by itself. At the time, I had 3/4 in my 36 gallon tank – so short about 54 lbs of fuel.

Assuming I weigh the truck by itself at a later date (with identical passengers, cargo, and fuel level), are there any other considerations I need to take into account aside from being aware of the missing weight when calculating payload?

I think that’s all you need to think about. I greatly prefer to do the weights together (especially as it’s cheaper because re-weighs within 24 hours at the same scale are only $2-3). But if you can try to keep everything consistent, the math should work out and you can run the numbers through TowingPlanner.com.

I didn’t realise that a re-weigh would let you weigh a different configuration so that’s good to know. I purchased a tongue weight scale from etrailer.com, it wasn’t cheap but I can measure the tongue weight quickly and accurately without leaving my drivewayand towing my trailer 80 mile round trip to a CAT scale just for that. I’ll pull into the CAT scale on my way to the campground. I’ve put the tongue weight scale on a local ‘for sale/rent’ website so I plan to rent it out to try to recover some of the $$$. I’m in Ontario, Canada so sorry I can’t bring it to the US! Thanks for the info.

A tongue scale is well worth the investment provided you have an idea of about how heavy the trailer is overall.

Great calculator. My question is that my result for the tongue weight percentage is 17.3% (1560 lbs tongue weight) and is based on the no weight distribution numbers. I calculate the percentage at 14.8% (1340 lbs.) using the with-weight distribution numbers. I had previously upgraded my receiver hitch and WDH to 2000 from 1500 so I’m covered either way on my upgrade.

My question is in determining capacities of the towing equipment. Is the without WD tongue weight the one to use or the with WD tongue the one for selecting equipment capacities?

Without WD tongue weight. The WDH doesn’t reduce the tongue weight, it just moves it around.

Can I Tow This?

Enter tow vehicle and trailer/RV information to determine if your setup is over its weight rating. After you click "Calculate," the results will appear at the bottom of the page. You can enter multiple vehicle-trailer combos, and the results will be listed sequentially, until you use the "Clear" button or refresh the page. No data is saved. (About this calculator.)

GCVWR = Maximum Allowable GCVW

GCVW = Truck Curb Weight + Driver + Passengers + Truck Cargo + Trailer Dry Weight + Trailer Cargo GCVW = visit a truck scale with your rig (ideal)

Payload = Driver + Passengers + Truck Cargo + Hitch

Payload Rating = Truck GVWR - Truck Curb Weight

Trailer GVWR = Trailer Dry Weight + Trailer Cargo

Definitions:

Vehicle curb weight, or dry weight: The weight of your vehicle (the one doing the towing) completely empty. No driver, no passengers, no cargo, no extra features, maybe even an empty gas tank. This can be found on a sticker inside the door frame, in the owner's manual, or elsewhere from the manufacturer. The only way to get an accurate curb weight is to take your vehicle to a weigh station and weigh it with no one and nothing in it.

GVWR, or Gross Vehicle Weight Rating: The maximum amount your vehicle can weigh, including all passengers, cargo, and the weight of the trailer hitch (see below). This is provided by the manufacturer on a door sticker, owner's manual, or other manufacturer's publication.

GCVWR, or Gross Combined Vehicle Weight Rating: The maximum amount the combination of vehicle and trailer can weigh, including all passengers, cargo, water and waste tanks, propane, food, and toys. This is provided by the manufacturer.

GCVW, or Gross Combined Vehicle Weight: The actual weight of the combination of vehicle and trailer, including all passengers, cargo, water and waste tanks, propane, food, and toys. The best way to get an accurate GCVW is by taking your vehicle and trailer to a weigh station.

Payload rating: The maximum weight that can be hauled inside the vehicle, including driver, passengers, cargo, and the hitch weight. A payload rating is published by the manufacturer, but can be calculated by finding the difference between a vehicle's GVWR and curb weight.

Payload: The actual payload is the combined weight of the vehicle curb weight, the driver, all passengers (including pets!), cargo, and the hitch weight.

Trailer Dry Weight: The weight of your trailer completely empty. Manufacturers' definitions of "empty" can vary widely, and may or may not include propane, water or waste tanks, or extra features added after manufacture. This number can be found on a sticker from the manufacturer. The only way to get an accurate dry weight is to take your trailer to a weigh station and weigh it empty.

Trailer GVWR, or Gross Vehicle Weight Rating: The maximum amount your trailer can weigh, including cargo, water and waste tanks, and propane. This is provided by the manufacturer on a door sticker or other manufacturer's publication.

Hitch weight: This is generally about 10% of the trailer's GVWR, but is also provided by the manufacturer. Getting an accurate hitch weight will result in a more accurate payload calculation.

Disclaimer: If you find any errors or omissions, I would be very grateful if you sent me an email so I can update this tool. I am not an expert in this topic, and I hope you'll do your own math to confirm what's offered here. Many factors go into safely towing a vehicle, including tire and axle weight ratings, which are not included in these calculations. This tool also assumes you have loaded your trailer to its maximum capacity, but no further. I offer this as a tool to aid you in your decision-making process, not as a towing expert or consultant. I hope this helps you and makes your life a little easier. Happy trails!

Weight and Balance Equations and Calculator For Trailers

Machine Design Equations, Applications and Calculators

This calculator will determine the Weigh and Balance of a trailer or similar application. Units used are in, lbs or mm and Newton's perspective. At the bottom of the webpages, there are several weight and balance application example's.

Conversion:

1 in = 25.4 mm 1 lbs = 4.44822 Newton's

Of course you can use kilograms in place of newton's. 1 kg = 9.80665 Newton'sor 2.2046 lbs (Whatever makes you happy).

To determine the center of balance (CB) and weight locations following the following procedure.

1. Use the following formula to compute the CB location of vehicles. Multiply weight by distance of each axle from the reference line (in inches), and then divide the total results by the vehicle gross weight. The resulting figure is the number of inches to be measured aft from the reference line to the CB of the vehicle.

Center of Balance Formula Wl -- Front axle weight. W2 -- Rear axle weight. DI -- Distance from RDL to front axle or center of articulated tandem axle D2 -- Distance from RDL to rear axle or center of articulated tandem axle.

2. The vehicle CB is computed to the nearest whole inch. Any answer with a fraction of .5 or higher is increased to next higher number. If .4 or less, drop the number.

Calculation example #1

Step 1. Weigh all axles individually. Step 2. Mark weight above each individual axle. Step 3. Establish the RDL at the forward edge of the vehicle. Step 4. Measure all distances from RDL to center of each individual axle. Step 5. Distance multiplied by weight equals a moment.

Example of basic formula for determining the CB.

(Dl x W1) + (D2 x W2) GROSS WEIGHT = CB from RDL

D I from RDL (from forward edge) to center of front axle = 20" W1 front axle weight = 2,870 lbs D2 from RDL (from forward edge) to center of rear axle - 150" W2 rear axle weight = 2,550 lbs

W1 (2,870 lbs) + W2 (2550 lbs) = Gross Weight (5,420 lbs) Total Moment (439,900) divided by Gross Weight = CB (81" from RDL) [(D1 (20") x W1 (2,870 lbs)] +[ (D2 (150" x W2 (2,550 lbs)] Gross Weight (5,420 lbs) = CB (81" from RDL)

Calculation example #2

[D1 (15") x W1 (250 lbs)] + [D2 (102") x W2 (2,250 lbs)] W1 (250 lbs) + W2 (2,250 lbs) = Gross Weight (2,500 lbs) = CB (93" from RDL)

Calculation example #3

[D1 (70") x W1 (12,500 lbs)] + [D2 (222") x W2 (12,900 lbs)] + [D3 (276") x W3 (12,700 lbs)] W1 (12,500 lbs) + W2 (12,900 lbs) + W3 (12,700 lbs) = Gross weight (38,100 lbs) = CB (190" from RDL)
