On The Road
Dinghy Towing
When a motorized vehicle is towed behind a
motor home with all four tires on the ground,
the towed vehicle is often referred to as a
"dinghy". Vehicle manufacturers produce tow-
able cars and bucks that are designed to be
capable of being towed behind a larger vehicle,
such as a motor home, with all wheels down.
Caution should be exercised when selecting a
vehicle for dinghy towing. If not, battery drain
on the electrical system could occur, the trans-
mission of the vehicle could be damaged, the
vehicle may be too heavy to pull, among other
concerns.
Before selecting the vehicle that will be towed,
consult the vehicle manufacturers instructions to
ensure the vehicle is approved by the manufac-
turer for dinghy (four wheels down) towing.
Any aftermarket products that modify the
dinghy for towing should also be approved by
the vehicle manufacturer.
Make sure that the dinghy weight and attaching
hardware do not exceed the motor home hitch
receiver rating. Make sure that the weight of the
motor home and dinghy together; do not exceed
the gross combination weight rating (GCWR) of
the motor home. Make sure that tow bars and
hitch equipment is rated to handle the weight of
the vehicle you intend to tow.
In addition, the dinghy must be equipped with
its own independent auxiliary brake system that
is activated any time the motor home brakes are
applied.
Because of StatelProvince regulations, care must
be exercised when wiring the dinghy for all
lighting requirements.
Check with the DMV of your State and/or
States (and Provinces) you will be traveling
through for their requirements.
