Howdy & Welcome --- Is that a "gasser" or diesel. Either way, it looks pretty clean. As for what to do with/to it...that is purely a subjective call. These rigs can be made over into just about anything. RV, camper, hunting lodge, taligater, mobile retirement home (my plan), taco wagon, toy hauler, mobile business...you name it. Just take your time, read up (and this is the best place for that)...and you'll come up with a dream/plan/vision that is your own. That's the beauty of this type of endeavor. It can be any damned thing you want!
Once again, welcome.
