I have the same coach but with the gas fridge. The batteries are awful. They lasted only 1 day while dry camping and I changed the lights over to LED. With a residential fridge forget about it..! I'm headed to the factory service next month to see if they can replace them with 2 12V deep cycle. I read in MH magazine that the 6v take forever to charge and its true. I run an external generator 12-14 hrs every other day to keep them charged.
