Dropped hunting off my recreational activities quite a few years ago... unless you count coyotes from the front porch at 150 yards.
I had an old pickup camper that I dropped on the ground and used as a base camp. It had 12 volt power, pitcher pump for water and LP for everything else. It is still at the hunt camp some 35+ years later. I gave it to a buddy of mine and he built a shelter over it. We did deer, turkey, dove, duck, geese and bear.
This is in the coastal plains of the Carolinas.
