Storage and Batteries

I've never had to store my RV before so I've always had access to electrical power for it. But on the occasion where I have let it sit for a month or so without being plugged in usually my chassis batteries go dead and the house batteries get weak.

To the question, I'm going to need to store my motorhome at an indoor facility I found, but they have no electrical to the units. So what's the best way to make sure I don't have dead batteries every time I go to use the motorhome? I have a disconnect switch for the house batteries and it seems to work well, but there is no similar switch for the chassis batteries. Is there an easy way to hook up a disconnect switch for the chassis battery or is it just as easy to remove the cables? With the cables removed should the batteries keep their charge for one to two months? I likely won't go that long between uses, but you never know.

Assuming your house and chassis batterys are fully charged and in good(decent) shape remove the negative posts and they will not(should not) be dead even at a year or so.Six months will be an assured no brainer
The ECU will not be effected at all. Upon hooking up batterys and after a short drive it will relearn all required settings and thats a FACT
