Truck-Camper Loading
Information
A vehicle-specific Truck-Camper
Loading Information label is
attached to the inside of the
vehicle's glove box. This label
indicates if a slide-in camper
can be carried, how much of a
load the vehicle can carry, and
how to correctly spread out the
load. It will help to match the
right slide-in camper to the
vehicle.
Your dealer can help make a
good vehicle-camper match and
help determine the Cargo
Weight Rating (CWR).
When installing and loading a
slide-in camper, check the
manufacturer's instructions.When carrying a slide-in
camper, the total cargo load of
the vehicle is the weight of the
camper plus:
.Everything added to the
camper after it left the
factory.
.Everything in the camper.
.All the people inside.
The CWR is the maximum
weight of the load the vehicle
can carry. It does not include the
weight of the people inside. But,
use about 68 kg (150 lb) for
each seat.
The total cargo load must not be
more than the vehicle's CWR.
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 in
zone 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:
