RE: RV Batteries Thank you everyone for your help/input. I bought 2 new 12 volt batteries, they are wired one to the next then into the RV. I have them plugged into the house for now as the camper is just sitting until the end of March. Once it gets warm enought here in NY to run water in the tanks and pipes we have some weekends planned. I figure with 2 full propane tanks, 2 fully charged 12 v battteries and a Honda EU3000 for use when needed, buy 2 night 3 day weekends should be securely powered. Just to throw a fly in the ointment, I was thinking about installing some small solar panels on the roof of the RV. I understand from the little investigation I have dome so far that they power primarilly 12V accessories. You can never have enought power or water. I would hate to run out of either.
