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 addi-
tional 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 should fall with-
in the truck’s recommended center of
gravity zone when installed.
CAUTION
Be careful—overloading can cause
dangerous braking and handling prob-
lems, and can damage your vehicle
and its tires.
