Now here's my idea of the ultimate 'go anywhere' camper: the
EarthRoamer XV-LT.
However, my needs may be a bit different than yours, primary need is a self contained 'go anywhere' machine suitable for flying 'solo', with on board "rest room" facility (Darn prostate (BPH) business, anyway!), kitchen gear is handy too in order to avoid having to head into 'town' from da boonies for restaurant food.
One small benefit is that the camper heat, hot water, and stove all powered by safe and efficient diesel fuel, there are
no propane tanks to deal with! See the
Camper Appliances.

XV-LT Systems.
Note that the absence of a propane tank also eliminates the hassle experienced in traveling through some highway tunnels where propane tanks are not allowed.
The only real problem is the $250,000.00 price tag. I guess I'll have to win da Powerball lottery first, eh?
I will concede a small advantage that the fifth wheel and other 'detachable' campers have over a 'motor home' or other self-contained unit: Ya can leave 'em at your campsite when you need to head into town for groceries, etc. with your tow vehicle instead of having to abandon the campsite and drive off with the entire rig.
