Porta-potties are fabulously convenient, especially since as you note, Deryk, one needn't move the whole shootin' match to make a trip to a (perhaps distant) dump station. Any toilet/outhouse will do!
Per the floor plan: great drawing, Steve! And speaking simply from my own multiple-uses-for-small-interiors perspective:
It occurs to me when looking at the drawing that one could perhaps use that "dropped floor" area for once-a-day shower purposes...seems like all one would need would be a circular ring for a curtain and a drain in the floor.
I just wonder how much smaller the
Scamp will be/feel once the shower wall is in and the front window blocked from the rest of the interior...
