■Overloading
Be careful — overloading can cause dangerous braking and handling
problems, and can damage your vehicle and its tires.

Gross axle and vehicle weight ratingsSecure 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 ax le 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 cert ification label which is located on
the door latch post on the left side of the vehicle. ( P. 668) If weight
ratings are exceeded, move or remove items to bring all weights
below the ratings.
