For owners
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
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. 543) If weight
ratings are exceeded, move or remove items to bring all weights
below the ratings.
