4.16 Hitching and Towing the Trailer
See Graphic: wc_gr003185
Before hitching and towing the trailer, check the following:
• Check that the vehicle, towing hitch, and coupler have a rating
equal to or greater than the trailer's Gross Vehicle Weight Rating
(GVWR). See
Technical Data for trailer weight.
• Check tread wear and inflation of the trailer’s tires. Make sure all
the lug nuts are in place and tight.
• Make sure that the trailer coupler and towing vehicle’s hitch are
compatible. The trailer is equipped with either a pintle-style cou-
pler or a 2" or 2-5/16" ball coupler.
• Check the condition of the trailer’s coupler and the hitch on the
towing vehicle. DO NOT tow the trailer if the coupler or the hitch
are damaged.
• Check that the coupler and the hitch ball are clean; then, apply a
film of grease to the coupler and the hitch ball. A film of grease
will extend the coupler and ball life and eliminate squeaking.
• Check that all the pins and bolts on the tongue are secure.
To hitch the trailer:
4.16.1 Back your vehicle as close as possible to the trailer. It is easier and
safer to back the tow vehicle under the trailer than to pull the trailer to
the vehicle.
4.16.2 Check that the coupler locking device (h) is released.
4.16.3 Raise the trailer coupler using the tongue jack (d) to a height just above
the ball on the hitch. Carefully position the vehicle so the ball on the
hitch is under the coupler. Lower the jack until the coupler is all the way
down over the ball.
4.16.4 Check under the coupling to be sure that the ball clamp is below the
ball and not riding on top of it.
4.16.5 Clamp the coupler to the hitch ball. To be sure it is clamped and
securely in place, raise up on the trailer tongue. If it comes loose from
the ball, release the ball clamp and repeat step 3.
4.16.6 After the trailer is hitched to the towing vehicle, lock the rear stabilizers
(k) and the tongue jack (d) in the UP positions.
4.16.7 Make sure the wiring harness (g) is connected to the vehicle and that
the tail, stop, and turn lights (e) and side marker lights (f) work.
4.16.8 Connect the safety chains (c) in a crossing pattern under the trailer
tongue.
