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 1
through the appropriate holes in the tongue and through
the holes in the tubular portion of the lunette eye (C, D,
Figure 10).
WARNING
Failure to secure the screws and nuts holding the combi-
nation trailer coupler and 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 tightly secure the screws holding the combina-
tion trailer coupler and lunette eye to the tongue.
5. Using new lock nuts, install nuts on the two hex head
screws and tighten.
6. Check the two hex head screws and lock nuts securing
the trailer coupler to the tubular portion of the lunette eye,
and make sure they are tight. If the screws or lock nuts
are loose, replace the lock nuts and tighten securely.

Connecting The Trailer To The Tow
Vehicle
1. Make sure that wheel chocks are placed on both sides of
each of the heater trailer’s wheels.
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” for detailed information on
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 11) to the tow vehi-
cle’s hitch frame. Cross the chains under the tongue as
shown in Figure 11. 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 to the tow vehicle’s
connector (B, Figure 11). 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 to the tow
vehicle. See “Break-Away Brake System” for detailed
information on the break-away brake system.
9. Retract the tongue jack all the way, and place the jack in
transport position. See “Operating The Tongue Jack” for
detailed information on operating the tongue jack.
10. Remove the wheel chocks from both sides of each of the
heater trailer’s wheels.
