Loading Your Vehicle
-
DSI/KPA (COL3)
The Certification/Tire label is found on the rear edge of the driver’s door or
in the Incomplete Vehicle Document in the cab.
The label shows the size of your original tires and the inflation pressures
needed to obtain
the gross weight capacity of your vehicle. This is called the
GVWR (Gross Vehicle Weight Rating). The
GVWR includes the weight of
the vehicle, all occupants, fuel and cargo.
The CertificatiodTire label also tells you the maximum weights for the
front and rear axles, called Gross Axle Weight Rating (GAWR).
To find out
the actual loads
on your front and rear axles, you need to go to a weigh
station and weigh your vehicle. Your dealer can help
you with this. Be sure
to spread out your load equally on both sides of the centerline.
Never exceed the GVWR for your vehicle, or the GAWR for either the front
or rear axle.
And,
if you do have a heavy load, you should spread it out.
A CAUTION-:
In the case of a sudden stop or collision, things carried in the bed
of your truck could shift forward and come into the passenger \
area, injuring you and
others. If you put things in the bed of
your truck, you
should make sure they are properly secured.

A CAUTION:
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.
If your vehicle is equipped
for front-end equipment (a snow plow, for
example), the front suspension may have been adjusted (raised) to level the
vehicle when the equipment was installed. If the front suspension was
adjusted,
you must re-adjust the front suspension after the equipment is
removed to avoid possible front suspension damage. Adjust the front
suspension to original design specifications for your particular model.
NOTICE:
Your warranty does not cover parts or components that fail
because
of overloading.
There’s also important loading information for off-road driving in this
manual. See “Loading
Your Vehicle“ in the Index.

Truck-Camper Loading Information
Open your glove box door and look for this label:
4-39
ProCarManuals.com

This label will tell you how much of a load your vehicle can carry, and how
to spread out your load the right way. Also, it will help you match the right
slide-in camper
to your vehicle.
When you carry a slide-in camper, the total cargo load
of your vehicle is the
weight of the camper,
PLUS
everything else added to the camper after it left the factory;
everything in the camper; and
all the people inside.
The Cargo Weight Rating (CWR) is the maximum weight of
the load your
vehicle can carry.
It doesn’t include the weight of the people inside. But,
you can figure about 150 pounds for each seat.
The total cargo load must not be more than your vehicle’s CWR.
TRUCK LOADING INFORMATION
1. Recommended
location
for cargo
center
of gravity
for cargo weight
rating (Pickup
Truck)
.
Refer to the Truck Camper Loading Information label in glove box for
“A”and
“B” dimensions. Use the rear edge of the load floor for
measurement purposes.

EXAMPLE OF PROPER TRUCK AND CAMPER MATCH
I. Camper center of
gravity
2. Recommended
center
of gravity
location zone.
The camper’s center of gravity should fall within the center
of gravity zone
for your vehicle’s cargo load.
You must weigh any accessories or other equipment that you add to your
vehicle. Then, subtract this extra weight from the
CWR. This extra weight
may shorten the center
of gravity zone of your vehicle. Your dealer can help
you with this.
If your slide-in camper and its load weigh less than the CWR, the center
of
gravity zone for your vehicle may be larger.
Your dealer can help you make a good vehicle-camper match. He’ll also
help you determine your CWR.
After you’ve loaded your vehicle and camper, drive
to a weigh station and
weigh
on the front and rear wheels separately. This will tell you the loads on
your axles. The loads on the front and rear axles shouldn’t be more than
either of the GAWRs. The total
of the axle loads should not be more than
the
GVWR.
Open your driver’s door and look at the CertificatiodTire label to find out
your
GAWR and GVWR.
If you’ve gone over your weight ratings, move or take out some things until
all the weights fall below the ratings.
Of course, you should always tie down
any loose items when you load your vehicle
or camper.
When you install and load your slide-in &‘@er, check the manufacturer’s
instructions.
If you want more information on curb weights, cargo weights, cargo weight
rating
and the correct center of gravity zone for your vehicle, your dealer
can help you. Just ask for a copy of “Consumer Information, Truck-Camper
Loading.”

Trailer Recommendations
You must subtract your hitch loads from the CWR for your vehicle. Weigh
your vehicle with the trailer hitch attached,
so that you won’t go over the
GVWR or the
GAM.
You’ll get the best performance if you spread out the weight of your load
the right way, and if you choose the correct hitch and trailer brakes.
For more information, see “Trailer Towing” in the Index.
Pickup Conversion to Chassis Cab
General Motors is aware that some vehicle owners may consider having the
pickup box removed and a commercial or recreational body installed.
Before you do
so, first contact the GM Zone Office for your area for
information on such conversions specific to this vehicle. (See \
the “Warranty
and Owner Assistance” booklet for Zone Office.) Owners should be aware
that, as manufactured, there are differences between a chassis cab and a
pickup with the box removed which may affect vehicle safety. The
components necessary to adapt a pickup to permit its safe use with a
specialized body should be installed by a body builder in accordance with
the information available from the Zone Office.
Towing a Trailer
Pulling a trailer improperly can damage your vehicle and result\

in costly repairs not covered by your warranty. To pull a trailer
correctly, follow the advice
in this part, and see your GM dealer
for important information about towing a trailer with your vehicle.
