The two most common types of recreational vehicle
towing are known as dinghy towing and dolly towing.
such as behind a motorhome.
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.
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 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. See Before Leaving on a
Long Trip on page 5 25.
