GCW (Gross Combined Weight)
- is the Gross Vehicle Weight plus
the weight of the fully loaded
trailer.
GCWR (Gross Combined
Weight Rating) - is the maximum
allowable weight of the vehicle
and the loaded trailer, including
all cargo and passengers, that the
vehicle can handle without risking
damage. (Important: The towing
vehicle's braking system is rated
for operation at Gross Vehicle
Weight Rating, not at Gross
Combined Weight Rating.)
Separate functional brakes should
be used for safe control of towed
vehicles and for trailers where the
Gross Combined Weight of the
towing vehicle plus the trailer
exceed the Gross Vehicle Weight
Rating of the towing vehicle. The
Gross Combined Weight must
never exceed the Gross
Combined Weight Rating.
Maximum Loaded Trailer
Weight - is the highest possible
weight of a fully loaded trailer the
vehicle can tow. It assumes a
vehicle with mandatory options,
driver and front passenger weight
(150 pounds [68 kilograms]
each), no cargo weight (internal
or external) and a tongue load of
10–15% (conventional trailer) or
king pin weight of 15–25% (fifth
wheel trailer). Consult an
authorized dealer (or the RV and
Trailer Towing Guide available at
an authorized dealer) for more
detailed information.
