Weight of the Trailer Tongue
The tongue load (A) of any trailer is an important weight
to measure because it affects the total or gross weight
of your vehicle. The Gross Vehicle Weight (GVW)
includes the curb weight of the vehicle, any cargo you
may carry in it, and the people who will be riding in
the vehicle. If you have a lot of options, equipment,
passengers or cargo in your vehicle, it will reduce the
tongue weight your vehicle can carry, which will
also reduce the trailer weight your vehicle can tow. And
if you will tow a trailer, you must add the tongue load
to the GVW because your vehicle will be carrying
that weight, too. See Loading Your Vehicle on page 4-50
for more information about your vehicle’s maximum
load capacity.
The trailer tongue weight (A) should be 10 percent to
15 percent of the total loaded trailer weight, up to
a maximum of 600 lbs (272 kg) for the 1500 or
2500 series, and up to a maximum of 750 lbs (340 kg)
for the 2500 HD or 3500 series with a weight carrying
hitch. The trailer tongue weight (A) should be 10 percent
to 15 percent of the total loaded trailer weight, up to a
maximum of 1,000 lbs (453 kg) for the 1500 series
and up to a maximum of 1,500 lbs (680 kg) for the
2500, 2500 HD or 3500 series with a weight
distributing hitch.
Fifth wheel or gooseneck kingpin weight should be 15 to
25 percent of the trailer weight up to the maximum
amount specified in the trailering chart for your vehicle.
See “Weight of the Trailer”, and “Fifth-Wheel and
Gooseneck Trailering” in this section.
