And, if you do have a heavy load, you should
spread it out.
CAUTION:

Do not load the vehicle any heavier than
the Gross Vehicle Weight Rating (GVWR), or
either the maximum front or rear Gross Axle
Weight Rating (GAWR). If you do, parts on the
vehicle can break, and it can change the way
your vehicle handles. These could cause you
to lose control and crash. Also, overloading
can shorten the life of the vehicle.

:
damage. Repairs would not be covered by your
warranty. Do not overload your vehicle.
The label will help you decide how much cargo
and installed equipment your truck can carry.
Using heavier suspension components to
get added durability might not change your weight
ratings. Ask your dealer to help you load your
vehicle the right way.
