Fifth-Wheel Hitch
The fifth-wheel hitch is a special high platform with a
coupling that mounts over the rear axle of the tow vehicle
in the truck bed. It connects a vehicle and fifth-wheel
trailer with a coupling king pin.
Your truck may be equipped with a fifth-wheel hitch option.
Refer to the separately provided fifth-wheel hitch safety,
care, assembly, and operating instructions.
Gooseneck Hitch
The gooseneck hitch employs a pivoted coupling arm
which attaches to a ball mounted in the bed of a pickup
truck. The coupling arm connects to the hitch mounted
over the rear axle in the truck bed.
