TWR (Trailer Weight Rating)
■
The maximum allowable gross
trailer weight. The gross trailer
weight is the sum of the trailer
weight and the weight of the
cargo in the trailer.
TWR is calculated assuming
base vehicle with one driver,
one front passenger, towing
package (if available), hitch and
hitch systems (if required).
Additional optional equipment, passengers and cargo in the vehicle will
reduce the trailer weight rating so as not to exceed GCWR, GVWR and
GAWR.
If the gross trailer weight exceeds 3000 lb. (1360 kg), it is recommended
to use a trailer with 2 or more axles.
Unbraked TWR (Unbraked Trailer Weight Rating)
■
The trailer weight rating for tow-
ing a trailer without a trailer ser-
vice brake system.
Tongue Weight

hitch ball. (→P. 181)
