9-22 Driving and Operating
When carrying a slide-in
camper, the total cargo load of
the vehicle is the weight of 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.

Refer to the Truck-Camper

Use the rear edge of the load
floor for measurement purposes.

point 3 for the CWR. It is the
point where the mass of a
body is concentrated and,
