360view - Wow, I could have walked out to the shop and disconnected all the batteries in the time it took to read that. wrench

Thanks everyone. In the last few decades I have tried everything from disconnect and forget to an old nothing fancy Schumacher maintainer. I think you guys are right. Not worth worrying about. I'll just disconnect them all. I might even bring in the coach batteries from my motorhome so that I can disconnect the shore power.

In theory, there is no difference between theory and practice. In practice, there is.
