If you have the ability to keep it plugged in while storing, just leave the use/store in the use mode. As was explained earlier there is always a drain even when the store switch is activated. I just replaced both of my house batteries after one died and the other was on it's way. They were 2017 batteries in my 2018 Thor Siesta. I replaced them with wet cell Marine 12 volt batteries that were on sale at our local auto parts shop.
