Chassis battery issue

I have a 2014 Winnebago sightseer. During the summer I have it parked at my cabin and plugged into 50amp shore power 24x7. After being gone for a couple weeks, I came back up and my chassis battery level basically drained(It's less than a year old). I know that if I store it, I need to switch the coach and chassis batteries off. But I thought as long as I was plugged into shore power, the chassis should keep a charge. The coach battery is normal. I was hoping to start the unit using the battery boost switch and charge the chassis battery, but that wouldn't work either. SUGGESTIONS appreciated....

THANKS

    You may have a parasitic drain killing the battery. Disconnect the NEGATIVE cable,

    May have?
    Most modern (Anything built this century or the last decade of the last one) will have computers and so on that draw current on or off.

    not much current but the average chassis battery only has about 10-15 amp hours to spare. Let's see 73amp hours times 20% is 14.6 and then you dead.
