Trailer Recommendations
You must subtract your hitch loads from the CWR for
your vehicle. Weigh your vehicle with the trailer attached,
so that you won't go over the GVWR or G A M .
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.
Camper Wiring Harness (Option)
A five-wire harness is stored in the front stake pocket on
the driver's side of the bed. The harness has no
connector and should be wired by a qualified electrical
technician. It must be routed out. of your vehicle and
securely attached so that it won't be pulled or rubbed
while you're using it. Store the harness in it's original
position. Wrap the harness together and tie
it
neatly so
it
won't be damaged.
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 Trail-r
If you don't use the correct equipment and drive
properly, you can lose control when you pull a
trailer. For example, if the trailer is too heavy, the
brakes may not work well
--
or even at all. You
and your passengers could be seriously injured.
Pull a trailer only if you have followed all the
steps in this section. Ask your GM dealer for
advice and information about towing a trailer
with your vehicle.
