You must subtract your hitch loads from the CWR for
your vehicle. Weigh your vehicle with the trailer

You’ll get the best performance if you spread out the

correct hitch and trailer brakes.

General Motors is aware that some vehicle owners may
consider having the pickup box removed and a
commercial or recreational body installed. Before you

components necessary to adapt a pickup to permit its
