It is perfectly normal for wet cell batteries to use distilled water if they are connected 24/7 to AC power.
The switches to turn off the power on my Scenic Cruiser are on the rear compartment on the passenger side.
I have the Freedom 458 inverter/charger and it trickle charges the batteries as needed, but you still have to check your batteries at least once a month.
AGM batteries are too expensive and are not as good as a lot of people lead you to believe. I had to replace the two chassis batteries last year and they were the sealed type (maintainance free). They cost me almost $400.00 installed at CW.
