Weight Of The Trailer Tongue - GMC Sierra 2010 Owner's Manual

Weight of the Trailer Tongue

The tongue load (A) 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 Loading the Vehicle
for more information about the vehicle's maximum
load capacity.
5-60
Trailer tongue weight (A) should be 10 percent to
15 percent and fifth wheel or gooseneck kingpin weight
should be 15 to 25 percent of the loaded trailer weight
up to the maximums for vehicle series and hitch type
shown below:

Do not exceed the maximum allowable tongue weight
for the vehicle. Choose the shortest hitch extension that
will position the hitch ball closest to the vehicle. This will
help reduce the effect of trailer tongue weight on the
rear axle.
