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 tongue weight. The total load must be
limited so that you do not exceed the GVWR.
Refer to "Vehicle Loading/Vehicle Certification
Label" in "Starting and Operating" for further
information.
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"
condition. 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 supported 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.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum capacity of the front
and rear axles. Distribute the load over the front
and rear axles evenly. Make sure that you do
not exceed either front or rear GAWR.
WARNING!
It is important that you do not exceed the
maximum front or rear GAWR. A dangerous
driving condition can result if either rating is
exceeded. You could lose control of the
vehicle and have an accident.
Trailer Tongue Weight (TW)
The TW is the downward force exerted on the
hitch ball by the trailer. In most cases it should
not be more than 10% of the trailer load. You
must consider this as part of the load on your
vehicle.
WARNING!
An improperly adjusted hitch system may
reduce handling, stability and braking perfor-
mance and could result in an accident. Con-
sult with your hitch and trailer manufacturer
or a reputable trailer/caravan dealer for ad-
ditional information.
Frontal Area
The frontal area is the maximum height multi-
plied by the maximum width of the front of a
trailer.
