It is easy to tell just by looking under the hood .
Draw on the chassis battery should be no different than your personal car. Do you put a maintainer on your car when parked on vacation?
My rig is parked from November to April, store switch on, inverter off. Except for a monthly start up and short ride around the block (weather permitting) .
Coach batteries always show 12+ and rig starts with no problems.

My Axis doesn't have a BIRD and it still charges the chassis battery when plugged in (its old enough to have the RV Custom Products board).
