My owner's manual doesn't list the truck I have so I can't get the towing/carrying capacities. Also, the Ford research dept. told me that they would send me all the info but all they sent was a towing brochure for 2002 Fords. Here's what I have: 1993 F350 regular cab dually, auto trans, 460 engine, 4.1 axle. I have been pulling a horse trailer, which when loaded with horses and gear, weighs 5000 pounds. I use a weight distributing hitch. I have put a cabover camper on the truck and the camper weighs about 2100 pounds when loaded. The truck has a GVWR of 10,000 pounds and weighs about 8200 pounds with passengers, gear, and camper. I want to make sure that I can pull the trailer with no problems now. I'm certain I can, but I would like to get the numbers anyway. Does anyone know what the GCWR is for my truck? Any help would be appreciated.
