WARNING
Towing a trailer with worn, damaged or underinflated tires
could result in death or serious injury. Always replace worn
or damaged tires promptly. Always keep tires inflated to
proper cold tire inflation pressure.
8. Use an appropriate means to support the trailer tongue.
Check that the tongue jack operates properly. See
‘Operating The Tongue Jack’.
9. Connect the trailer coupler or lunette eye to the tow vehi-
cle trailer hitch or pintle hook. Connect the safety chains
and trailer lighting connector to the tow vehicle. See
‘Connecting The Trailer To The Tow Vehicle’ for detailed
information.
10. Make sure all covers and doors are closed and securely
latched.
Trailer Coupler / Lunette Eye
The heater trailer can be equipped with either a standard
adjustable-height trailer coupler or lunette eye. The SAE
J684 trailer coupler for a 2-5/16 inch / 59 mm diameter ball
is rated at 15,000 pounds (6,804 kg) GVWR with a 2,250
pound (1,021 kg) tongue weight. The 3-inch (75 mm) diama-
ter lunette eye, conforming to the requirements of SAE J847,
is rated at 25,000 pounds (11,340 kg) GVWR with a 3,000
pound (1,361 kg) tongue weight.
To change between the trailer coupler and lunette eye:
1. Check the tongue, trailer coupler and lunette eye for
missing and damaged parts. Replace any part that is
missing or damaged.
2. Remove the two lock nuts and hex head screws ( A ,
Figure 6) securing the trailer coupler ( B ) or lunette eye
( C ) to the tongue. Discard the lock nuts.
3. Select either the trailer coupler or lunette eye (whichever
is required to couple the heater trailer to your tow vehi-
cle), and position it at the front of the tongue. Determine
the height which works best for your tow vehicle.
4. Insert the two hex head screws removed in Step 2
through the appropriate holes in the tongue and trailer
coupler or lunette eye.
5. Install new lock nuts (Grade 5 or stronger) onto the two
hex head screws and tighten securely.
WARNING
Failure to securely tighten the hardware securing the trailer
coupler or lunette eye to the heater trailer tongue could
cause the heater trailer to separate from the tow vehicle,
resulting in death or serious injury. Always check and
securely tighten the hardware holding the trailer coupler or
lunette eye to the tongue.

Connecting The Heater Trailer To The
Tow Vehicle
1. Place wheel chocks (not supplied) against the front of the
front wheels, and against the back of the rear wheels, on
both sides of the heater trailer.
2. Use the tongue jack to raise the trailer coupler or lunette
eye above the tow vehicle’s hitch ball or pintle hook. See
‘Operating The Tongue Jack’.
3. Position the tow vehicle’s hitch ball or pintle hook under
the trailer coupler or lunette eye.
4. Lower the trailer coupler or lunette eye onto the hitch ball
or pintle hook with the tongue jack.
5. Lock the trailer coupler or pintle hook. See ‘Using The
Trailer Coupler’ or ‘Using A Pintle Hook’ for detailed cou-
pling information.
6. Attach the safety chains ( A , Figure 7) to the tow vehicle’s
hitch frame. Cross the chains under the tongue as
shown in Figure 7. Leave enough slack in the chains to
allow for turns, but not so much that the chains will con-
tact the road surface.
7. Connect the trailer lighting connector ( A , Figure 8) to the
tow vehicle’s connector ( B ). Make sure the trailer lighting
harness has adequate length to prevent disconnection
when turning, but not so much length that the harness
will contact the road surface. Check the stop, turn sig-
nal, tail, side marker and license plate lamps for proper
operation.
8. Connect the break-away brake switch cable ( C , Figure 8)
to the tow vehicle ( D ). See ‘Break-Away Brake System’
for detailed information on the break-away brake system.
9. Raise the tongue jack all the way, and retract the jack
foot into the transport position. See ‘Operating The
Tongue Jack’.
10. Remove the wheel chocks from both sides of the heater
trailer wheels.
