Other side of the country....
I also have started looking at small enclosed trailers...maybe something 6ftX10. The only problem is that it would be 6ft high to accomodate my height and that's TOTALLY not practical offroad even though it's about as tall my Jeep LOL.
They are beefy, have a rear and side door, couldn't be TOO hard to add a window, right? Easy enough to mount a few dome lights, build a few drawers and table for kitchen area. Raised area with foam pad for sleeping area. It just doesn't fold n go, but it sure hitches n goes.
Might depend on how balsy you are with it too....I just heard a story about a place where guys in huge dually trucks pulling 30ft rv trailers would floor it up a hill, hit the trailer brakes and slide around obstacles on sand because it was too tight a turn...takes guts. LOL
For example: add the aforementioned items and do a SOA...not bad, eh?
