TWR (Trailer Weight Rating)
The maximum allowable gross

weight is the sum of the trailer

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 vehi-
cle will reduce the trailer weight
rating so as not to exceed GCWR,

If the gross trailer weight exceeds
3000 lb. (1360 kg), it is recom-
mended to use a trailer with 2 or
more axles.
