Preparing to tow
Use the proper equipment for towing a trailer and make sure it is
properly attached to your vehicle. See your dealer or a reliable trailer
dealer if you require assistance.
Hitches
Do not 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 20%-25% fifth-wheel towing of the total weight of
the trailer is on the tongue.
Integrated hitch rating
The standard integrated 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.
