Thanks for the advice. I have no problem being ridiculous about gear and mods. I’m probably going to stick to just two group 31 125 Ah batteries at this point. I thought about a 200 Ah Li battery, but the weight savings to cost just didn’t make sense at this junture. (Thanks Mike for the article about Li batteries.)
I haven’t looked at any of the inverters yet. Can one attach (2) pair of heavy cables to them? Probably depends on the brand. Time to start figuring the wiring diagram for this thing. I hate having the camper in our storage unit and not having easy access to it, but this has been one of the epic winters we sometimes get here.
