(a) GCWR is the maximum allowable combined weight of loaded truck and trailer. It includes the weight of passengers, cargo and fuel in the truck and cargo in the trailer. (b) Maximum Trailer Weight = GCWR – Curb Wt. – 150 lbs. (allowance for driver) and must be decreased by the weight of optional equipment, trailer hitch, cargo, and passengers. Maximum trailer weights shown are rounded to the nearest 50 lbs. less. Use synthetic axle lubricant with the trailer tow package. Tongue weight should be 10-15% of loaded trailer weight but may not cause vehicle to exceed GVWR or GAWR. Load equalizing hitch recommended for trailers over 2000 pounds. (c) With optional Twenty-inch Wheel and Tire Sport Group.
