I'm a little different than everyone else! I leave my coach plugged in 24/7/365 and have been doing this since 1976 and it works just fine for me! I check and clean the batteries once a month (House Batteries) my chassis battery (engine) is sealed so I just clean the top and the cables. I also have a solar trickle charger that keeps my batteries refreshed. Good Question and you will get many different answers! It won't take long as a owner to try different things too see what works for you best.
