Check the trailer ball height — Make certain that the
trailer ball height is 18 inches, plus
or minus one inch. Ball heights
outside of this range can create
poor towing characteristics, such
as sway and fishtailing.
In addition, incorrect ball height
can cause the ramps to damage
the bottom of the towed vehicle or drag on the road
over bumps and dips.
The coupler requires a two-inch hitch ball with a
5,000 lb. capacity.

The instructions on the following pages contain
references to various components of the tow dolly. Use
Figure 6 (above) to familiarize yourself with their names
before reading the ‘Using your tow dolly’ section.
2.
Check the tread width — Before attempting to load
the towed vehicle, measure the tread width (see the
‘Axle and ramp positioning' chart below) and make cer-
tain that the ramps and axles are in the correct position
for the towed vehicle.
See the preceding assembly sections for detailed
instructions on how to adjust the width of the ramps
and axles.

Check the vehicle weight — The RoadMaster tow
dolly is rated to haul a maximum of 4,250 pounds.
Verify that the weight of your towed vehicle and all of
its contents does not exceed 4,250 pounds.
