Common Towing Definitions

The following trailer towing related definitions
will assist you in understanding the following
information.
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your
vehicle. This includes driver, passengers,
cargo and trailer tongue weight. The total load
must be limited so that you do not exceed the
GVWR.
Gross Trailer Weight (GTW)
The GTW is the weight of the trailer plus the
weight of all cargo, consumables and equip-
ment (permanent or temporary) loaded in or on
the trailer in its loaded and ready for operation

The recommended way to measure GTW is to
put your fully loaded trailer on a vehicle scale.
The entire weight of the trailer must be sup-
ported by the scale.
Gross Combination Weight Rating (GCWR)
The GCWR is the total permissible weight of
your vehicle and trailer when weighed in com-
bination.
