2004 Southwind 37c electrical switches in bathroom

[Mudhen 462]

Hello,
Recently bought my motor home and the fellow I bought it from was the original owner. He didn't know much about it, did not know that the water heater could be run on either 120 v or propane. Anyway, it has 2 switches in a bathroom cabinet (seen in the picture). They feel like three way switches, stops at the top, middle and bottom. When you move the switches some things work and others are shut off, depending on where the switches are set. I can not find anything on the operation of these switches in any of the manuals that I have. I'm hoping that someone can shed some light on this for me.

Your coach has a 30 amp cord. It can not provide enough amperage to use the washer and dryer and the microwave and Elec. hot water heater at the same time. You have to choose which appliances you want to use.
