Rear Bumper; Fifth Wheel Pin Box (Customer Supplied) - Jayco SEISMIC 2021 Owner's Manual

Section 3: Pre-Travel Information

Rear Bumper

The rear bumper of your RV is not designed to carry cargo. Items that extend beyond the
bumper OR weigh over 100 lbs. (45kg) will place undo strain on the bumper. The 100 lb.
bumper capacity includes the weight of the spare tire (if so equipped).
Do not add items to the recreation vehicle rear bumper. Add-on items will
eventually damage your bumper. Damage caused by such aftermarket equip-
ment installation or improper loading voids the Towable Limited Warranty.
NOTE: Some items may fall within the given weight range, (IE: bike racks)
however, they can still cause damage. In addition, extra weight behind the
axle may reduce the hitch weigh which can adversely affect handling.

Fifth Wheel Pin Box (customer supplied)

Hitch selection affects the towing and handling characteristics of your recreation vehicle.
There are many kinds of hitches available and assuring that you have the correct hitch in-
stalled is critical to a safe towing.
Ask your dealer about the proper class and type of hitch you need to purchase for your indi-
vidual 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 class rating based on the capacity that hitch has for towing and a weight classifica-
tion. 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.
Using an oversized or undersized hitch can cause damage to the RV frame. We
(as your RV manufacturer) cannot be responsible for the tow vehicle suspen-
sion 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 over-
loading 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.
Your recreation vehicle manufacturer 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 pin box height, stability and levelness of a hooked up
dealer is aware of the tow vehicle you are using so a compatible hookup is achieved.
