Thanks for all the good info re running a residential frig while dry camping. I had another look at the brochure I have for the motorhome we're interested in. It says it has a Maytag 22 c.f. frig with a 2000 watt (not 1000 as I thought) pure sine inverter and two batteries (doesn't say what kind) dedicated specifically to the frig. We will have four 80 watt panels installed (we have them now on our present motorhome) and, yes, we will have a generator. What I'm wondering -- would it work to have a solar panel and regulator installed, specifically dedicated to the frig?
