If you were to Resto-mod a TC, what what you do?

Replace frame with aluminum.
Smooth siding (as opposed to the aluminum siding mine has)
Move wet bath up front and position things more ergonomically.
Basically make the rest of it a garage not unlike a toy hauler. Just brainstorming what I think would be cool. Realistically, the logistics of storage and being fully self contained would get in the way of the toy hauler idea.

Lightweight as possible though!
