Time - his TC is just a shell.
Last summer I went up and taught him to fish (wiring, electrical, plumbing).
At this point, he's got a starter battery, a wiring harness (which I showed him how to wire from).
We added a small sink to wash his face in (and an easly swappable 5 gallon drinking water jug) - oddly enough it came with a solar panel and a charge controller (which we wired in).
But - he's reaching the point where his starter battery is failing and he can't fully recharge the battery because his charger is a trickle charger - hence my question.
He'll never have a "typical" TC with a fridge, a power distribution panel and a converter (120v to 12v) like most of us have.
If he had a vectron or something of that class, it would last him a lifetime. Add a couple of GC batteries and he'd have power for days.
