consider before recreational vehicle
towing:
.What is the towing capacity of
the towing vehicle? Be sure to
read the tow vehicle
manufacturer's
recommendations.
.What is the distance that will be
travelled? Some vehicles have
restrictions on how far and how
long they can tow.
.Is the proper towing equipment
going to be used? See your

towed? Just as preparing the

the vehicle is prepared to be
towed.
Dinghy Towing
Front-wheel‐drive and
all-wheel-drive vehicles may be
dinghy towed from the front. These
vehicles can also be towed by
placing them on a platform trailer
with all four wheels off of the
ground. For other towing options,
see“Dolly Towing” following in this
section.
For vehicles being dinghy towed,
the vehicle should be run at the
beginning of each day and at each
RV fuel stop for about five minutes.
This will ensure proper lubrication of
transmission components.
To tow the vehicle from the front
with all four wheels on the ground:
1. Position the vehicle that will be towed and secure it to the
towing vehicle.
2. Turn the ignition key to ACC/ ACCESSORY.
3. Shift the transmission to N (Neutral).
