Driving and Operating 323Ask your dealer for trailering
information or advice.
Weight of the Trailer Tongue The tongue weight 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. In general, trailer tongue weight (1)
should be 10 – 15% and fifth-wheel
or gooseneck kingpin weight should
be 15 – 25% of the loaded trailer
weight (2). Some specific trailer types, such as boat trailers, fall
outside of this range. Refer to the
trailer owner ’ s manual for the
recommended trailer tongue weight.
In all cases, do not exceed the
maximum loads for the vehicle
series and hitch type.
