Like you we have been fortunate that our oem Chassis and House batteries are still running strong. I do know, that in the Axis there are a couple things that drain the battery ...which some may not be aware of. The radio in the dash seems to run off the Chassis battery and if you do not turn it off when shutting down the motor it will remain on....you must hold in the on/off button until it totally shuts off. Also, in the Axis 21 … the Jensen radio in the bedroom has a back light which remains on unless you go into settings and turn it off. Little things like this will drain the battery.
We, unfortunately, let our chassis battery drain after returning home in Sept after an extended trip....Fortunately, it took the hour plus charge … and during this cold weather we are having...we start the Axis daily to make sure it is doing well.
