That is what the bath tub, a 5 gallon stock pot, and LPG/NG stove top is for. Heat water on the stove and take a bath. Has everyone forgotten how to camp? No electricity? Just go in “camping mode” psychologically. That home is a very very nice “tent”.
I have camped in the woods, in the mountains, at lakes, and beaches. I have also camped at home, but prefer not to; thanks.
