From the OP: Although likely not the problem of 'dead batteries', I found that the on/off switch for the house batteries was stuck in the 'on' position and would not turn off (per little green light). So, decided to take it in to CW for (likely) a new switch and to locate cause of batteries draining. Thanks for comments...
If the coach is plugged into shore power (or the generator is running) and the AC-DC converter/charger is energized the light will not go out since the converter is providing DC power to the coach. Similarly when converter is producing DC power you can not tell the state of the disconnect in since the light will not change. You may think the batteries are connected and getting a maintenance charge but they may not be and with time will self discharge. Maybe the this is what caused the initial problem?
Good information. I'll follow up on your comments/advice. Thanks!
Additionally, even though the coach is new the batteries could be on their last leg. Very rare for a dealership to plug a coach in to maintain a good charge level. Also manufactures don't always install ture deep cycle batteries for the coach side. Add the two together and throw in a couple to deep discharge/charge cycles while waiting on the sales lot and your batteries may be at their end of useful life.
