Truck-Camper Loading Information
-
The Truck Camper Loading label is located inside your
glove box. 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
to your vehicle.
-
When you carry a slide in camper, the total cargo load
of your vehicle is the weight of the camper, plus
D
everything else added to the camper after it left
the factory,
D
everything in the camper and
D
all the people inside.
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 lbs. (68 kg) for each seating position.
The total cargo load must not be more than your
vehicle's CWR.
Refer to the Truck
glove box for dimensions A and B as shown in the
following illustration.

Use the rear edge of the load floor for measurement
purposes. The recommended location for the cargo
center of gravity is at point C for the 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.
