Refer to the Truck-Camper
Loading Information label in the
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.
Here is an example of proper
truck and camper match:

Driving and Operating
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 (A) should fall within
the truck's recommended center
of gravity zone (B) when
installed.
