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.

These are hitch ratings only; actual vehicle ratings are dependent on
engine, transmission and axle combinations.
WARNING: Towing trailers beyond the maximum tongue weight
exceeds the limit of the towing system and could result in
vehicle structural damage, loss of vehicle control and personal injury.

Your vehicle is equipped with a removable trailer hitch trim cover. To
remove the trim cover:
1. Loosen the two 1 ⁄
