I don't see any issues with leaving it plugged in all the time as opposed to pulling the batteries and putting them on a maintainer. The new RV convertors trickle as well as a maintainer. It's a lot easier to leave the batteries in and plugged in. Why unhook them (2 G24's), pack them to where ever, then when the season gets going again, drag them back out and hook them back up if you can simply run an electrical cord to your RV? If I didn't have power where the 5'er is parked then yes I would drag them out and hook to a maintainer.
That's why I leave mine plugged in 24/7.
