Good arguments both ways. Considering these responses, and the fact that I don't leave my camper plugged in over the winter, I think I'll continue to do what I've always done. That is, remove the battery, keep it down in the "mancave" on a block of wood and monitor it over the winter, attaching the charger when necessary. That said, I have never removed the battery from my lawn tractor, which sits in the shed covered up all winter. I am still using the original battery, which was new in 1999. I guess it's true: Nothing runs like a Deere!
