I should have tested the batteries, but we were blocking someone's way to get to work and we had to get on the highway, so we jumped it and took off. Our house batteries seemed fine. The fridge was working, all lights still turned on in the coach. However, the chassis battery was completely drained (would not start).
Sorry for my lack of terminology. To clear things up, we have a Freedom 10 inverter that's wired to two house batteries, and from there, it goes up to the chassis battery with an isolator between. Now I'm a bit freaked about leaving my inverter on at all. Some of my research has made me think a Xantrex ECHO battery charger may help?
