Truck-Camper Loading Information The Truck-Camper Loading label is located on the passenger's door near the latch. It will tell you if your vehicle can carry a slide-in camper, how much of a load your vehicle can carry, and how to correctly spread out your load. Also, it will help you match the right slide-in camper to your vehicle. When the truck is used to carry a slide-in camper, the total cargo load of the truck consists of the manufacturer's camper weight figure, the weight of installed additional camper equipment not included in the manufacturer's camper weight figure, the weight of camper cargo, and the weight of passengers in the camper. The total cargo load should not exceed the truck's cargo weight rating and the camper's center of gravity should fall within the truck's recommended center of gravity zone when installed. The Cargo Weight Rating (CWR) is the maximum weight of the load your vehicle can carry. It doesn't include the weight of the people inside. But, you can figure about 150 Ibs. (68 kg) for each seating position. The total cargo load must not be more than your vehicle's CWR. Refer to the Truck-Camper Loading Information Label on the passenger's door for dimensions A and B as shown in the following illustration. t Use the rear edge of the load floor for measurement purposes. The recommended location for the cargo center of gravity for the Cargo Weight Rating (C) is the point where the mass of a body is concentrated and, if suspended at that point, would balance the front and rear. 4-52
