Gross Combination Weight Rating (GCWR)
The gross combination weight rating (GCWR) is the total
permissible weight of your vehicle and trailer when
weighed in combination. (Note that GCWR ratings in-
clude a 150 lbs (68 kg) allowance for the presence of a
driver).
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.
Tongue Weight (TW)
Tongue Weight (TW) is the downward force exerted on
the hitch ball by the trailer. In most cases it should not be
less than or more than 10% of the trailer load. You must
consider this as part of the load on your vehicle.
Frontal Area
Frontal Area is the maximum height and maximum
width of the front of a trailer and its cargo.
Weight-Carrying Hitch
A weight-carrying hitch supports the trailer tongue
weight, just as if it were luggage located at a hitch ball or
some other connecting point of the truck. These kinds of
hitches are the most popular on the market today and
they're commonly used to tow small- and medium-sized
trailers.
