Compare these two measurements. For car-mounted tow
bars, they must be approximately equal; for motorhome-
mounted tow bars, they cannot be more than three inches
apart if the base pin is above or below the motorhome hitch
receiver, as shown in Figure 2.
Towing with a tow bar which is not within the Safe Zone
will void the ROADMASTER warranty.
Towing a vehicle with a tow bar that is not within the
Safe Zone will result in significant wear and tear on the
tow bar and brackets, significant wear and tear on the
vehicle’s suspension and frame, and the eventual failure
of the towing system.
Do not drill a second hole in the shank of the hitch
receiver, tow bar or hitch receiver extension. Drilling
a second hole will weaken the steel. The shank may
break during towing, which will cause the towed ve-
hicle to separate. Refer to Figure 1.
If the pre-drilled holes do not align to the hole in
the hitch receiver or the extension: 1) purchase a hitch
accessory of the appropriate length; or 2) call ROAD-
MASTER technical support.
Figure 1
The primary purpose of a hitch receiver adaptor or exten-
sion of the type discussed in these instructions is to bring
the tow bar to level — into the ‘Safe Zone.’ Car-mounted tow
bars must be approximately level; motorhome-mounted tow
bars cannot be more than three inches above or below level.
Towing with a tow bar which is not within this range puts
undue strain on the entire towing system. For that reason,
do not tow if the tow bar is not within the Safe Zone.
To determine if the tow bar is within the Safe Zone — first,
connect the motorhome and vehicle on level ground. Next,
measure the distance from the center of the motorhome
hitch receiver down to the ground. Then measure the dis-
tance from the center of one of the base pins (Figure 2)
on one of the tow bar arms (Figure 2) down to the ground.

Stay within the ‘Safe Zone!’

Do not use the hitch receiver extension if it drags
going over dips, railroad tracks or other uneven road
surfaces. The steel will be severely weakened by the
force of the impact, which will cause the shank (Figure
1) to break.
Inspect the bottom of the extension after the initial
use, and after each trip thereafter, to make certain that
it has not come into contact with the road.
