Tires, Wheels and Loading
Hitches
WARNING: ON PICK-UP TRUCKS, the trailer hitch provided on
this vehicle enhances collision protection for the fuel system. DO
NOT REMOVE!
Do not mount a ball hitch (sometimes referred to as a trailer ball hitch
or trailer ball) to the bumper or use hitches that clamp onto the vehicle's
bumper or attach to the axle. You must distribute the load in your trailer
so that 10%–15% for conventional towing or 15%-25% fifth-wheel towing
of the total weight of the trailer is on the tongue.
Hitch rating
The standard hitch has two ratings depending on mode of operation:
• Weight carrying - requires a draw bar and hitch ball. The draw bar
supports all the vertical tongue load of the trailer.
• Weight distributing - requires an aftermarket weight distributing
system which includes draw bar, hitch ball, spring bars and snap-up
brackets. The vertical tongue load of the trailer is distributed between
the truck and the trailer by this system.
