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.
Gross axle weight rating
Front GAWR Rear GAWR
Secure loose items to prevent weight
shifts that could affect the balance of your
vehicle. When the truck camper is loaded,
drive to a scale and weigh on the front
and on the rear wheels separately to de-
termine axle loads. Individual axle loads
should not exceed either of the Gross
Axle Weight Ratings (GAWR). The total of
the axle loads should not exceed the
Gross Vehicle Weight Rating (GVWR).
These ratings are given on the vehicle
Certification Label which is located on the
door latch post on the left side of the
vehicle. See “Your Toyota’s identification”
in Section 2 for the Certification Label
location. If weight ratings are exceeded,
move or remove items to bring all weights
below the ratings.
