I would not leave my batteries merged. There are two different schools of thought on this. My reason is that if you lose the plug in power, both banks will be depleted. But I also have an echo charger that charges the chassis batteries from the house batteries, so the chassis batteries have some charge that way without the risk of killing every battery on board.

I am assuming since you are going to tape the slide openings that you will not run the air compressors in storage?

I turn the water pumps off, nothing good can happen with them on.
