GMC 1997 Safari Owner's Manual page 205

Do not load your vehicle any heavier than the
GVWR, or either the maximum front or rear
GAWR. If you do, parts on your vehicle can
break, or it can change the way your vehicle
handles. These could cause you to lose control.
Also, overloading can shorten the life of
your vehicle.
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.
NOTICE:

components that fail because of overloading.
If you put things inside your vehicle -- like suitcases,
tools, packages, or anything else
--
they will go as fast
as the vehicle goes. If you have to stop or turn quickly,
or if there is a crash, they'll keep going.
