I am some what surprised there is till info available on the old trucks for hauling truck campers.Ford and Starcaft RV teamed up and made a large fiberglass TC(10+ feet?) for the new Super Camper special weighing in at about 2900 lbs without gear which was about the same for the rest of the large TC's..
Made for serious campers looking for extra hauling capacity, a compliant ride, and conveniences like a built-in pigtail for easy trailer hookups and a sliding rear bumper that adjusted to aftermarket camper overhangs, the Super Camper Special was a plug-and-play camper conversion dream.
Ford started by increasing the wheelbase to an astounding 140 inches on a narrower eight-inch-tall, one-ton frame, with a single Dana 70 full-floating rear axle and twin I-beam front. Available only as a two-wheel drive single cab, the extended wheelbase made for a stable, better-riding truck with less camper intrusion, which eliminated the space normally reserved for the spare behind the rear axle. Ford fixed this with a secret compartment and detachable body panel on the passenger side of the bed for spare tire storage.
