Tires, Wheels and Loading Hitches Do not use hitches that clamp onto the vehicle's bumper or attach to the axle. You must distribute the load in your trailer so that 10%-15% for conventional towing or 15%-25% fifth-wheel towing of the total weight of the trailer is on the tongue. Integrated hitch rating The standard integrated hitch has two ratings depending on mode of operation: • Weight carrying - requires a draw bar and hitch ball. The draw bar supports all the vertical tongue load of the trailer. • Weight distributing - requires an aftermarket weight distributing system which includes draw bar, hitch ball, spring bars and snap-up brackets. The vertical tongue load of the trailer is distributed between the truck and the trailer by this system. Maximum Gross Trailer Weight - lb. (kg) 6000 (2721) 15000 (6804) Maximum Tongue Weight - lb.
