Refer to the Truck-Camper Loading Information label in glove box for dimensions A and B as shown in the following illustration. Here is an example of proper truck and camper match: A. Camper Center of Gravity B. Recommended Center of Gravity Location Zone Use the rear edge of the load floor for measurement purposes. The recommended location for the cargo center of gravity is at point C forthe CWR. It is the point where the mass of a body is concentrated and, if suspended at that point, would balance the front and rear. The camper's center of gravity should fall within the center of gravity zone for your vehicle's cargo load. You must weigh any accessories or other equipment that you add to your vehicle. Then, subtract this extra weight from the CWR. This extra weight may shorten the center of gravity zone of your vehicle. Your dealer can help you with this. If your slide-in camper and its load weighs less than the CWR, the center of gravity zone for your vehicle may be larger. 4-64
