Matt,

Are you throwing the battery disconnect switch when you leave the coach. For the chassis batteries, it's in the stainless panel in the right rear bay with the batteries.

For the house batteries, it is located in the bay with the house batteries.

Neither of mine will stay charged for more than about three weeks IF I leave them connected because of parasitic loads. (like Steve said, clocks, and radios, and such)

I do not store my coach plugged in.

Some will probably chime in about using an echo charger if you do store plugged in.
