Hitch selection is important because it affects the towing and handling
characteristics of your RV. There are many kinds of hitches available for various
uses and assuring that you have the correct hitch installed is critical to a safe
towing experience.
Ask your dealer about the proper class and type of hitch you need to purchase for
your individual tow vehicle/RV combination. A fifth wheel requires a pin box hitch
bolted directly to the floor of the truck box through the frame.
The hitch manufacturer assigns a hitch class rating based on the capacity that
hitch has for towing and a weight classification. The weight classification is
determined from the hitch's weight carrying capacity (the pin box weight on a fifth
wheel). Before selecting a hitch, you must know your GVWR and pin box rating.
The rating of the hitch package purchased should be equal to or greater than the
RV's GVWR and the pin box rating.
The rating of the hitch package purchased should be equal to or greater than
the RV's GVWR and pin box rating.
Using an oversized or undersized hitch can cause damage to the RV frame.
Jayco cannot be responsible for the tow vehicle suspension system. The final
ball height after the tow vehicle/fifth wheel combination is completely hooked
up is a factor that must be considered. To avoid overloading your trailer axles
and minimize possible handling difficulties, your trailer should be level when
hooked to your tow vehicle. Do not overload your tow vehicle.
Equipment that sometimes gives autos, trucks and sport utility vehicles a softer
ride can accentuate swaying when pulling a RV; conversely, suspension that is too
stiff will increase vibration, bounce and accelerate wear of your tow vehicle and
RV combination.
Jayco cannot be responsible for the suspension system of any tow vehicle.
There are a variety of tow vehicle suspension systems available that will
affect the ball height, stability and levelness of a hooked up RV.
Make sure your dealer is aware of the tow vehicle you are using so a compatible
hookup is achieved.

proper pin box weight on the hitch.
Fifth wheel pin box height
There is no recommended hitch height for fifth wheels; usually the fifth wheel pin
box is adjustable for variance in trucks and truck suspension systems.
Adjust the hitch assembly so the tow vehicle and the fifth wheel are essentially
level. A high hitch will transfer weight behind the axles and cause the vehicle to
fishtail.
A low hitch will transfer additional weight to the hitch.
