Weight of the Trailer
How heavy can a trailer safely be?
Speed, altitude, road grades,
outside temperature, special
equipment, and the amount of
tongue weight the vehicle can carry
must be considered. See Weight of
the Trailer Tongue later in this
section for more information.
Maximum trailer weight is calculated
assuming only the driver is in the
tow vehicle and it has all the
required trailering equipment. The
weight of additional optional
equipment, passengers and cargo
in the tow vehicle must be
subtracted from the maximum trailer
weight.
Use the following chart to determine how much the vehicle can weigh,
based upon the vehicle model and options.

*The Gross Combination Weight
Rating (GCWR) is the total
allowable weight of the completely
loaded vehicle and trailer including
any passengers, cargo, equipment
and conversions. The GCWR for the
