Enclosed trailer to be camping trailer?

I have seen many more cargo trailers converted to travel trailers in the Toy hauler world. From what I have seen most cargo trailers are made to haul a considerable amount more weight that a typical travel trailer and use sturdier axles which I would consider a plus. I think I have even come across some factory converted cargo trailers.

Cargo trailers come in various interior heights. At 6'3" myself I would want one with a 7' interior height. Those V noses have got to help with wind resistance considerably.
