The switch is a battery disconnect switch. It turns off the battery power so that things that don't have on-off switches don't drain the batteries when in storage (like the propane CO detector.) So, if you are plugged into shore power, or running the generator, or driving down the road, you will normally want the switch ON. This will provide power to things like the fridge, etc. It will also allow power to the batteries so they can be recharged.
When boondocking, or traveling down the road without the generator running, you can run the refrigerator, the furnace, all interior lights, the radio, the TV (in most Sunseekers the TV is 12 volt). The refrigerator will need propane on--the battery power is for the control circuit, not for cooling. The water heater can be run on propane. The water pump will run on 12 volt (battery) and, if equipped, the holding tank heaters (called Arctic Pack). What you can't run is the Air Conditioning, Microwave, and any appliances like coffee pots, etc.
I don't have a way to plug in when at home, because I park in a storage yard. So a day before a trip, I turn on battery and propane, and pre-cool fridge on propane. During winter, I leave the batteries in and start both the engine and the generator about once a month and let them run for awhile. This not only puts some charge on the batteries, but it is also very important to run the generator and not let the gas sit in the carburetor all winter.
