Step 2 - Install the Hitch Ball
Never exceed the specified weight ratings for the trailer, tow vehicle, hitch,
hitch ball, or any other towing equipment.
Install a properly-sized hitch ball onto the hitch head. The hitch ball diameter must
match the trailer coupler size.
Select a ball with either a 1” or 1-1/4” diameter threaded shank. If your hitch ball
has a 1” diameter shank you must use an appropriate bushing. Make sure that the
ball has a weight rating equal to or greater than your trailer’s gross vehicle weight
(GVW). Always use a lock washer against the nut, unless otherwise specified by ball
manufacturer. Torque the nut to the ball manufacturer’s specifications.

Step 1 - Ready the Tow Vehicle and Trailer
Check and inflate the tires on both the tow vehicle and trailer to their proper
pressures before setting up the hitch.
Park the trailer and tow vehicle on level ground and in line with each other. Chock
and uncouple the trailer. Pull the tow vehicle forward to allow about five feet of
working area in front of the trailer, and set the parking brake.
Ideally, when installing or adjusting the hitch, the tow vehicle and trailer should be
loaded just as they will be while traveling. This includes full propane and fresh water
tanks, and any other cargo (passengers & gear) the tow vehicle or trailer will carry,
including ATVs for toy haulers. If fully-loaded is not possible, set the hitch up for the
trailer as-is, and make adjustments later if needed.
If your tow vehicle is equipped with an auto-leveling suspension, or suspension air
bags, carefully read and follow the instructions in Appendix C - Installing With
Auto-Level/Air Bags on p. 28 as you set up and use your hitch. Also review your
tow vehicle owner’s manual for specific information about using your auto-leveling
system while towing.
your trailer load, perhaps even during the same trip. For example, a trailer that
starts with full clean water and propane tanks may tow differently when that water
becomes black and grey water, and the propane tanks are empty. Or, a trailer loaded
with gear for a long cross-country trip may tow differently than the same trailer
loaded for a weekend getaway. The driver must be conscious of these changes, and
adjust the hitch accordingly.
