No generator, no solar. Hoping driving around will power the house batteries. It won't? Am I walking myself into a corner?

I guess a 1-2000 watt generator is also something I have to fork out the money for. I have no Toad and any generator needs to stay in the coach with me.

Your engine will trickel charge that battery. but if you are looking at staying in a remote location for several days, do you want to have to run the engine for several hours a day to charge the coach battery?
