Camper Towing: Choosing The Right Size For Your Vehicle

how big of a camper can I tow

When it comes to towing a camper, there are several factors to consider in determining the maximum weight your vehicle can handle. Firstly, understanding the tow rating capacity of your vehicle is critical. This involves paying attention to the automobile's Gross Vehicle Weight Rating (GVWR), which is typically found on a sticker inside the driver's side door frame. The GVWR represents the maximum weight your vehicle should tow.

Additionally, when calculating the towing capacity, you need to take into account the weight of passengers, cargo, liquids, and any added accessories. This is crucial for safety and performance. It's important to consult with specialists or refer to resources like towing guides to ensure you have the right tow vehicle and camper combination.

Furthermore, there are various weight designations and abbreviations to be aware of, such as Dry Weight/Unloaded Vehicle Weight (UVW), Gross Vehicle Weight (GVW), Gross Combined Weight Rating (GCWR), and more. These terms represent different aspects of the vehicle's and camper's weight, including the weight of the empty vehicle, the combined weight of the vehicle and trailer, and the maximum allowable weight of the tow vehicle-camper combination.

When deciding on the size of the camper you can tow, it's essential to consider not only the weight but also the tongue weight, which is the weight applied to the hitch. Ensuring that your vehicle's tongue weight capacity is not exceeded is vital.

Lastly, it's recommended to follow the 80/20 rule of towing, which suggests towing a camper with a GVWR that is no more than 80% of your vehicle's maximum towing capacity. This leaves a buffer for passengers, cargo, and variable driving conditions.

Understanding your vehicle's tow rating capacity

Firstly, it is important to note that the maximum towing capacity of a vehicle is determined by the vehicle manufacturer and takes into account the Gross Vehicle Weight Rating (GVWR), the Gross Axle Weight Rating (GAWR), the Gross Trailer Weight (GTW), and more. The GVWR is the maximum loaded weight of a vehicle, while the GAWR is the maximum weight that can be placed on the vehicle's front or rear axles. The GTW is the total weight of the trailer and its cargo.

The towing capacity of a vehicle is the maximum amount of weight it can safely pull, and this changes based on how the vehicle is configured, how much weight it's already carrying, and how you distribute and control the load. It is important to note that published towing specifications assume the vehicle carries only the driver, not any passengers or gear. Therefore, it is recommended to stay below 10% of the maximum towing capacity to account for miscalculations and shifting loads.

To calculate your vehicle's towing capacity, you need to know the full Gross Combined Weight Rating (GCWR) of the vehicle and the trailer, together with all the cargo each will carry. Then, subtract the curb weight (the weight of the vehicle itself with all necessary fluids) from the GCWR to get the vehicle's towing capacity.

Other key terms to be aware of include:

  • Braked Towing Capacity: The maximum weight a vehicle can tow when the trailer has its own braking system.
  • Unbraked Towing Capacity: The capacity of a vehicle to tow a trailer without its own braking system.
  • Tongue/Hitch Weight: The weight or pressure applied from the trailer tongue/coupler to the hitch on your vehicle.
  • Pin Weight: The weight or pressure applied from the fifth-wheel king pin to the hitch in the bed of your truck.
  • Payload Capacity: The amount of weight a truck can safely add to its bed. This must not exceed the payload capacity amount provided by the vehicle's manufacturer.

Always confirm your specific tow vehicle's towing capacity directly from the vehicle's manufacturer before purchasing or towing an RV.

The weight of your camper

  • Dry Weight/Shipped Weight: This refers to the weight of the camper as shipped from the manufacturer, excluding any passengers, cargo, liquids, or additional accessories. It is similar to the curb weight of a vehicle.
  • Gross Vehicle Weight (GVW): This is the combined weight of the camper (dry weight) plus passengers, cargo, and liquids.
  • Gross Vehicle Weight Rating (GVWR): This is the maximum allowed weight of the camper, including passengers, cargo, fluids, etc. The GVW should not exceed the GVWR.
  • Cargo Weight: This is the total weight of all passengers, food, clothing, liquids, accessories, and other items that you put into the camper.
  • Tongue/Hitch Weight: This is the weight or pressure applied from the trailer tongue/coupler to the hitch on your vehicle. It should typically be 10-15% of the camper's GVW.
  • Pin Weight: This refers to the weight or pressure applied from the fifth wheel king pin to the hitch in the bed of your truck.
  • Payload Capacity: For trucks, this is the amount of weight that can be safely added to the bed of the truck. It includes the hitch weight, pin weight, and any other accessories in the bed of the truck. It must not exceed the payload capacity specified by the manufacturer.

When considering the weight of your camper, it is important to remember that the GVWR of the camper is not the only factor. The weight of passengers and cargo in your tow vehicle will also reduce your maximum towing capacity. Therefore, it is crucial to calculate carefully and leave a buffer to account for wind, weather, and other driving conditions. Additionally, factors such as tongue weight, number of passengers, elevation, and the distribution of weight in your camper can impact the suitability of your tow vehicle.

The weight of your passengers and cargo

When calculating the weight of your passengers and cargo, it's important to remember that this will impact your vehicle's maximum towing capacity. This includes the weight of passengers, food, clothing, liquids, accessories, and any other cargo you plan to bring on your trip.

To calculate the weight of your passengers and cargo, you can use the following formula:

Cargo Weight = Weight of Passengers + Weight of Food + Weight of Clothing + Weight of Liquids + Weight of Accessories + Weight of Other Cargo

It's important to be as accurate as possible when calculating the weight of your passengers and cargo. Underestimating this weight could lead to exceeding the maximum towing capacity of your vehicle, which can have serious safety implications.

Additionally, it's worth noting that the weight distribution within your vehicle and trailer can also affect towing performance. An uneven weight distribution can cause trailer sway, making it difficult to control the vehicle, especially at high speeds. Therefore, it's crucial to distribute weight evenly and secure all cargo properly before towing.

By considering the weight of your passengers and cargo and distributing weight appropriately, you can ensure a safer and more enjoyable towing experience.

Tongue weight

If the tongue weight is too little, less than 10% of the total trailer weight, the trailer may sway from side to side, making it difficult to control. Conversely, if the tongue weight is too much, more than 15% of the total trailer weight, it can overload the rear tires of the tow vehicle, affecting handling and braking. The trailer may also sway in this case due to reduced control for the driver.

To measure tongue weight, you can use a tongue weight scale, a common bathroom scale, or a vehicle scale. Tongue weight scales are available at most towing supply shops and are designed specifically to measure tongue weight. A bathroom scale can be used for smaller trailers, and a vehicle scale can be used to weigh the vehicle with and without the trailer attached, subtracting the two weights to get the tongue weight.

For conventional trailers with ball-mounted hitches, the proper tongue weight is roughly 10 to 15% of the total loaded trailer weight. For example, a 2,000-pound conventional trailer loaded with 1,000 pounds of cargo should have a tongue weight between 300 and 450 pounds. Gooseneck and fifth-wheel trailers, designed for larger loads, have a proper tongue weight of between 15 and 30% of the loaded trailer weight.
