Driftwoodgal,
If you leave plugged in ALL the time you might not need a disconnect. But, if it gets unplugged and you don't realize it, well, there goes the battery. Ours is plugged in most of the time, but there are times it must be unplugged for more than 15 minutes and the disconnect is our savings.
We have used the slides on battery, IF the battery is charged, there is no problem. One summer we had it unplugged, disconnect off, slides open, tornado and severe storm warnings, I went out, turned the disconnect to ON, went in, closed slides, turned disconnnect back to OFF, went in the stick house. Easy. And, no storm!
