Hello Laurie,
When you plug in the 30 amps, the fridge will switch automaticaly to electric if you push the auto button on the fridge.
The furnace is always propane.
Your generator is always propane and, good news, it required a lot less maintenance than gas or diesel.
Your AC is always electric 110 volts.
Your fan above stove is electric 12 volts, it will work even if you are not plugged.
Your stove is always propane, the burners and the stove.
Your water heater is propane but you can switch it to electric but you have to know what you are doing, wait a little while for this

Well, I think that's it !
