The GCWR for the vehicle should not be exceeded. (b) This model is neither designed nor intended to tow fifth-wheel or gooseneck trailers. Ask your dealer for trailering information or advice. 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 " Vehicle Load Limits" for more information about the vehicle's maximum load capacity. Trailer tongue weight (A) should be 10 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.
