Gross Trailer Weight (GTW)
The GTW is the weight of the trailer plus the weight of all
cargo, consumables and equipment (permanent or tempo-
rary) loaded in or on the trailer in itsloaded 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 combination.
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. Refer to “Vehicle Loading/Vehicle Certifica-
tion Label” in “Starting And Operating” for further infor-
mation.
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.
Tongue Weight (TW)
The tongue weight is the downward force exerted on the
hitch ball by the trailer. You must consider this as part of
the load on your vehicle.
Frontal Area
The frontal area is the maximum height multiplied by the
maximum width of the front of a trailer.
Trailer Sway Control — Electronic
Refer to “Electronic Brake Control System/Trailer Sway
Control (TSC)” in “Starting And Operating” for further
