Had the real deal super c for 12 years. Had fun. Funmover 39c 40 ft, ford f750 chassis c7 caterpillar engine. About 7.5 mpg towing a 4 door jeep, back of the rig was a garage for carrying motorcycles, atv's sleeping and shop work.
It was fun while bit lasted. Big, tough to get into some places I now enjoy. An advantage not much discussed was the chassis maker ford built a solid product. Wires and such were where they belonged, serviceable at many ford places.weighed about 33k rolling down the road plus towed.real silid, never met a hill it liked! On ours the cab over was the master suite. You buy these for the carrying capacity. If you don't need it there's no advantage.
