Weight of the Trailer Tongue
The tongue load (A) of any trailer is an important weight
to measure because it affects the total gross weight
of the vehicle. 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. If there are a lot of options, equipment,
passengers or cargo in the vehicle, it will reduce the
tongue weight the vehicle can carry, which will also
reduce the trailer weight the vehicle can tow.
If towing a trailer, the tongue load must be added to
the GVW because the vehicle will be carrying that
weight, too. See Loading the Vehicle on page 4-30
for more information about the vehicle’s maximum
load capacity.
If a weight-carrying hitch or a weight-distributing hitch
is being used, the trailer tongue (A) should weigh
10-15 percent of the total loaded trailer weight (B).
After loading the trailer, weigh the trailer and then the
tongue, separately, to see if the weights are proper.
If they are not, adjustments might be made by moving
some items around in the trailer.
Trailering may be limited by the vehicle’s ability to carry
tongue weight. Tongue weight cannot cause the
vehicle to exceed the GVWR (Gross Vehicle Weight
Rating) or the RGAWR (Rear Gross Axle Weight
Rating). The effect of additional weight may reduce
the trailering capacity more than the total of the
additional weight.
