Weight of the Trailer Tongue
The tongue load (1) of any trailer is
very important because it is also
part of the vehicle weight. The
Gross Vehicle Weight (GVW)
includes the curb weight of the
vehicle, any cargo carried in it,
and the people who will be riding
in the vehicle as well as trailer
tongue weight.

Vehicle options, equipment,
passengers and cargo in the vehicle
reduce the amount of tongue weight
the vehicle can carry, which will also
reduce the trailer weight the vehicle
can tow. See Vehicle Load Limits on
page 9-15 for more information
about the vehicle's maximum
load capacity.
