I have bought a new winnebago vista. when storing for a month or so, since I have access to 30 amp service, is it better to leave the RV connected to service and use the batterie disconnet both chassie and coach. Or just unplug and disconnect? Can the batteries overcharge if I leave it connected to shore power?
As a rule of thumb, you're better off leaving the coach connected to shore power and leaving the batteries connected. Also, you'll need to install a small automatic battery tender to the engine batteries since the inverter/converter normally only charges the house batteries. Normally, overcharging is not an issue although a defective or incorrectly set inverter/converter could do just that.
The problem with disconnecting the batteries is they slowly loose their charge which shortens their live(s). Most of use don't use our coaches often enough to keep the batteries charged up, unlike our cars.
