2004 yellowstone

[CAddleman]

We recently purchased a 2004 5th wheel yellowstone and didn't recieve a walk through, but
are pretty knowledgeable about RVs and have owned for quite a while. On the electrical panel
where you can check water levels etc. there is another switch that is not labeled and can't seem
to figure what it means. It is not the hot water heater or battery and there are no solar panel.
What are we missing?

If it's a small switch it could be for the water pump. If it looks like a normal light switch in a house it's the ceiling fan.

Thanks Timothy, but the switch is not for the pump or the ceiling fan....

Are you sure it's not the water heater? On my unit ther is a switch for electric operation of the water heater as well as LP.
There also is a switch outside on the water heater that has a small safety pin to keep it from operating on electric if the hot water tank is empty, this switch has to be turned on too for electric operation.

The only other thing I can think of is possible heat blankets on your tanks, the switch might turn on the tank heaters. It also could be for some type of night lighting along the floors, you probably would have noticed that, unless the bulbs are burned out.
