Payload are a critical concept for anyone who uses a truck to carry a camper. Many people assumes that the towing capacity of a truck determines how much a truck can carry, but towing capacity and payload capacity are different measurement. Payload capacity is the maximum amount of weight that a truck can carry on the chassis, the suspension, and the tire of the truck.
To calculate the payload capacity, you must subtract the curb weight of the truck from the Gross Vehicle Weight Rating, which is often called the GVWR. You can find the GVWR on a yellow sticker located inside the driver’s side door frame of the truck. You should use the number found on the sticker because the sticker provide the accurate payload capacity for you truck.
How Much Your Truck Can Carry and How to Choose a Camper
The payload capacity must account for many different type of weight. You must include the weight of the camper in your payload calculation, and you must also include the weight of all gear, the weight of all water, and the weight of all people sitting in the truck cab. If the weight of the camper is nearly equal to the payload capacity of the truck, then the truck will have very little remaining payload capacity for gear or people.
Many people make the mistake of purchasing a camper that is too heavy for the payload capacity of there truck, and this mistake mean that the people cannot carry any additional supplies. Different type of campers require different types of truck because different campers have different weight. Lightweight pop-up campers are often suitable for half-ton trucks, but heavy hard-sided campers often require three-quarter-ton or one-ton truck.
If a person put a heavy camper on a small truck, the truck may experience poorly steering and poorly braking. Therefore, you must match the weight of the camper to the payload capacity of the truck to ensure that the truck can steer and brake correct. The design of a camper also affect the weight and the stability of the truck.
A cabover camper places a bed over the truck cab, and a cabover camper raise the center of gravity of the camper. A pop-up camper or a slide-in flat camper keep the weight lower to the ground, and a lower center of gravity help the stability of the truck. Additionally, luxury feature in a camper can increase the weight of the camper.
Large freshwater tank, heavy batteries, and solid construction are all features that increase the weight of the camper and decrease the remaining payload capacity of the truck. You must manage weight throughout the entire trip because weight is an ongoing concern. For example, water is a heavy substance because one gallon of water weigh over eight pounds.
Many travelers choose to keep their water tanks empty while they are driving so that the truck remain light, and these travelers fill the water tanks only when they reach their destination. Additionally, you can reduce the weight of the camper by using lithium battery instead of lead-acid battery because lithium batteries are more lighter than lead-acid batteries. Safety depend on how you distribute the weight and how you secure the camper.
You must use a proper tie-down system with turnbuckles and anchor point to secure the camper to the truck. You may also need to add helper spring or air bag to the suspension of the truck to prevent the rear end of the truck from sagging under the weight of the camper. If the rear end of the truck sag, the steering of the truck will become light and the steering will become dangerous.
Thus, you must respect the payload capacity of the truck and you must plan for the weight of the camper to ensure that the truck remain safe.
