Towing & Leveling
Hitch Height & Hitch Ball
To determine your RV hitch height, make sure the RV is level.
When the loaded trailer is hitched to the tow vehicle, check
the hitch ball height by measuring the distance from the center
of the hitch ball to the ground. Record your RV hitch height
measurement in the box for future reference.
•
To adjust the weight-distributing hitch to the proper
height, refer to the hitch manufacturer instructions.
• Adjust the equalizing bars of the hitch assembly until
the tow vehicle and the RV are essentially level.
• A
HIGH hitch
will transfer weight behind the axles and
cause the RV to fishtail.
• A
LOW hitch
will transfer additional weight to the hitch.
Your required hitch ball size is stamped on the hitch coupler.
Depending on your floor plan, your travel trailer requires a
hitch ball diameter of either 2” or 2

Sway Control
(Customer Supplied)
Aftermarket sway control devices are available to reduce the
sway produced by crosswinds, air displacement caused by
other vehicles passing you in transit, incorrect weight distribution,
excessive speed, the RV tires dropping onto the shoulder of the
road, etc. The use of a sway control device will help to control
the side-to-side movement and keep sway in check.
Suggestions for sway situations:
• Slowly ease your foot off the accelerator.
• Turn the steering wheel as little as possible.
◦
Natural lag time reaction when counter-steering
to correct sway could possibly make it worse .
• If the trailer is equipped with electric brakes, using the
hand control will help to keep the vehicles aligned.
• As soon as possible, stop to determine the cause of the sway.
◦
Check all equipment and load distribution.
◦
If the problem cannot be solved immediately,
contact your dealer for a service appointment.
• Travel at a much reduced speed on your way there
.
An aftermarket sway control
device (customer supplied)
and weight distributing
system (customer supplied)
should be used with your
tow vehicle/travel trailer
towing combination. Ask
your dealer for assistance
to help ensure proper
equipment installation for
your needs.
