Wondering if anyone can help me out with this problem. We have a 2003 Coachmen Leprechaun, our reserve battery doesn't seem to hold a charge. There is room under the stairs for two batteries, and when we bought the coach it only had one battery, and the manual doesn't give much info on that topic at all. We took the coach cross country last summer, and put two batteries under the stairs, they ended up boiling up and smelling like sulfur. Since then we only have one battery in there. Any info on this would be appreciated!
