Consult your dealer or a
professional towing service if the
disabled vehicle must be towed.
To tow the vehicle behind another
vehicle for recreational purposes,
such as behind a motor home, see
Recreational Vehicle Towing
following.
Recreational vehicle towing means
towing the vehicle behind another
vehicle such as behind a motor
home. The two most common types
of recreational vehicle towing are
known as dinghy towing and dolly
towing. Dinghy towing is towing the
vehicle with all four wheels on the
ground. Dolly towing is towing the
vehicle with two wheels on the
ground and two wheels up on a
device known as a dolly.
Here are some important things to
consider before recreational vehicle
towing:
What is the towing capacity of
the towing vehicle? Be sure to
read the tow vehicle
manufacturer's
recommendations.
How far will the vehicle be
towed? Some vehicles have
restrictions on how far and how
long they can tow.
Does the vehicle have the
proper towing equipment? See
your dealer or trailering
professional for additional advice
and equipment
recommendations.
Is the vehicle ready to be
towed? Just as preparing the
vehicle for a long trip, make sure
the vehicle is prepared to be
towed.
If the vehicle is towed with all four
wheels on the ground, the
drivetrain components could be
damaged. The repairs would not
be covered by the vehicle
warranty. Do not tow the vehicle
with all four wheels on the
ground.
