Recreational Vehicle
Towing
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:
.Before towing the vehicle,
become familiar with the
local laws that apply to
recreational vehicle towing.
These laws may vary by
region.
.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.
Caution
Use of a shield mounted in
front of the vehicle grille
could restrict airflow and
cause damage to the
electric drive unit. The
repairs would not be
covered by the vehicle
warranty. If using a shield,
only use one that attaches
to the towing vehicle.

Multi-Point Vehicle
Inspection (MPVI)

Inspection (MPVI) completed
by a GM dealer technician is a
maintenance assessment of
your vehicle. The benefit of
the MPVI is to identify and
inform the customer of service
items that require immediate
attention and those that may
require attention in the future.
The technician will perform the
following checks on your
vehicle. For a complete list of
checks, inspections, and
services, see your dealer.
