But an RV is also way bigger and heavier.

RV panels make sense for the boondocking use case, where you want to charge computers or power a satellite internet terminal or something, but I can't imagine actually trying to drive on that trickle of juice.

Agreed. There’s an EV camper van with rooftop solar. IIRC it gets about 1000W peak, which isn’t bad for the home batteries but is basically nothing for the high voltage drive system

How about charging your house batteries, which power fans and lights and perhaps cooking and A/C? This kind of solar setup can be rather cheap and quite effective.

[mikepurvis]

Yes, that's what I'm meaning. AIUI off-grid camping tends to be more limited by the drinking water supply more than electricity, but if collecting solar power lets you avoid running the generator quite as often, that sounds like a win.

This and you could also charge an ebike

Boats have been doing this for ages.
