Bill, you're quite possibly going to have similar problems in future. Here are a couple of things I'd be inclined to do if I'd had your problems:
1. If you have wet cel batteries, have you checked the water level and made absolutely sure that the plates are covered?
On my 2000 Tourmaster, I have an isolation switch for the house batteries by the entrance stairs to the coach. I always leave it turned off when I'm absent. I also have an isolation switch for the chassis (starting batteries) located on the furthest aft compartment on the passenger side. I leave it turned off any time I'm in a position in which not having an engine starting battery would leave me stranded.
