Ask your dealer/retailer for our trailering information or
advice, or write us at our Customer Assistance
Offices. See Customer Assistance Offices on page 7-5
for more information.
Weight of 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.
Axle Ratio Maximum Trailer Weight
3.42 8,600 lbs (3 900 kg)
Axle Ratio Maximum Trailer Weight
3.42 8,400 lbs (3 810 kg)
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 4-34 for more
information about your vehicle's maximum load capacity.
