Lobstah... The switches do indeed isolate the batteries from their circuits. Meaning of course turning them off will kill the power, and also prevent anything from draining them. To be honest I can't remember which is which but I think "Main" is the house batteries and "Aux" is the chassis battery. But I could be wrong, the way to tell is turn on one of your ceiling lights and flip a switch, the one that causes the light to go out is the Coach batteries.
Also, the Coach batteries, the two under the steps is what powers the generator. The Chassis battery, in front of the engine only controls engine and automotive functions.
Remember even when you think nothing is on you still have devices pulling current from your coach batteries. The propane detector, the carbon monoxide detector, etc. Which brings me to the question, when was the last time you tested your batteries? I mean a load test. I assume you do check the water level from time to time. Do you still have the factory converter or have you changed it out to a good state of the art Inverter/Charger with multi-level charging? The stock converters are very poor chargers and will overcharge batteries and ruin them.
