For owners
When the truck is used to carry a slide-in camper, the total cargo load
of the truck consists of the manu facturer’s camper weight figure, the
weight of installed additional ca mper 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 sh ould
not exceed the truck’s cargo weight rating and the camper’s cen ter of
gravity should fall within the truck’s recommended center of gr avity
zone when installed.

WARNING
■Loading precaution
If a load is too far back, it can cause dangerous handling. If it is too far for-
ward, the front axle may be overloaded.

For owners
Secure loose items to prevent weight shifts that could affect the bal-
ance 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
determine axle loads. Individual axle loads should not exceed e ither
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 le ft side of the vehicle. (P. 541) If weight
ratings are exceeded, move or remove items to bring all weights
below the ratings.

WARNING
■ Overloading
Be careful — overloading can cause dangerous braking and handli ng prob-
lems, and can damage your vehicle and its tires.
