■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 r ecommended
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)

Tongue Weight
If using a weight distributing hi tch when towing, return the front
axle to the same weight as b efore the trailer connection.
If front axle weight cannot be measured directly, measure the
front fender height above the front axle before connection. Adjust
weight distributing hitch torque until front fender is returned to the
same height as b efore connection.
The gross trailer weight, gross axle weight and tongue weight
can be measured with platform sca les found at a highway weigh-
ing station, building supply company, trucking company, junk
yard, etc.
