Ours styes hooked up and inside. They check the batteries,every two weeks or more often if something suggest they should, which the controller has on trickle charge. Could probably cut them off. You can't put it away and not check things like the batteries hooked up or not. I like it hooked up because it is ready to go when we arrange to get there. Food is in the refrigerator or at least some and ready to go. If it should get too cold the heat pumps would kick in. No water in the tanks though unless we are expecting to leave soon.
Stored unplugged,if you have auto gen start, the batteries get low, the generator will kick on and charge things up, if batteries are in condition. Stored inside they wouldn't want too many generators running.
