While many RV's will charge both battery banks from either power source, most that do have some sort od delay system.
My Monaco, and the Fleetwood we has first both had such a system. The power source would charge "it's primary battery" (engine alternator = chassis battery, converter = house battery) until it was nearly charged, and then energize the boost relay to charge the other bank.
Relying on this system to charge both banks while in storage isn't practical.
Do the voltmeter test, and use a real portable battery charger to charge the chassis batteries if you need to.
I never run my diesel onan in the winter, ever.
And if I don't have power in my winter storage place, I pull all the batteries and take them home to somewhere warm. If you can't pull the batteries out (why not? Should be possible to find someone to do the heavy lifting if that is the problem?) then disconnect the negative cables and let them be.
