Believing electricity central to self-containment is a categorical mistake.
Propane is what matters. Followed closely by fresh water capacity.
Propane is what makes camping in this way at all possible.
Electricity is third-order. Needed for furnace fan and (maybe) water pump.
That’s it.
Boondocking? It wasn’t conventional boxes taken the length of Africa or across the Soviet Union sixty years ago, it was Airstream.
And, too expensive? That’s funny They’re cheaper today. It’s you who’ve had a 50% pay cut the past fifty years (family income against productivity).
A trailer with an indefinite lifespan and/or 250k road miles versus a fall-apart that’ll be in the landfill before the finance note is completed (and maybe 75-80k miles).
It’s pretty well impossible to put out an electrical fire with what’s proposed. No thanks
