When I went to Boy Scout Camp with my sons I slept in a tent and cooked outside; that was fine. But I absolutely refused to use the latrines and would walk any distance to find a flush toilet. 30 years ago I didn't care all that much, but not now.
I also downsized from 2,900sf to 2,400sf. Of course, the new place cost 4x as much as the old; so I am not sure downsizing is the right word. (5 flush toilets).
But back to the OP; if your friend didn't have a well, what does he do for water?
