For the mass market RV, what is now called Super C showed up in 2003 with the introduction of the third generation General Motors Kodiak/Topkick platform, continuing on with lightweight International platforms when General Motors left the medium duty truck market as one of the provisions of the Federal bailout.
Since then, their have been similar offering on Ford MDT platforms (F-550, F650), International, and Freightliner "Business Class" chassis, DOT weight classes 5 and 6.
Many of the RV industry Super-C models were not diesel. For most Chevy/GMC offerings the Vortec 8100 V-8 was offered in preference to the 6.6 liter Duratec (about $10,000 difference in price), and for similar cost reasons your will usually find Ford chassis Super Cs with the 6.8 liter Triton V-10 rather than a PowerStroke diesel, or a larger Cummins as one goes up in chassis size. However, anyone building Super-C on International or Freightliner chassis, the engine will be diesel, just not one you might find in a diesel pickup truck.
Well before the RVIA Suoer-C era, Dynamax had been building motorhomes on DOT class 5 to class 8 chassis, and several custom converters have been building living units on DOT class 6 to class 8 chassis since time eternal. As since none of these converters are RVIA members, their products are not RVIA Class C, of which Super-C is a subset. It is another market entirely, just as entertainer coaches, and crew road coaches, are not RVs.
Towing capacity of a DOT class 8 conversion can be upwards of 60,000 pounds, assuming you can keep the chassis and house down to 20,000 or less. You have 40 tons of GCWR to work with, how much for the house, how much for the tow, you work that out when you plan your custom build. Set aside a couple million dollars.
