Let me start first by saying I am new to camper/camping but a veteran in boating, the 12 volt life, tent camping. I am enjoying coming up with more ways to live off the grid with this camper in the WV mountains and having a great time. Now that I tackled a problem with the fridge and the whole propane startup system which I had, I keep noticing this switch like a light switch, on the dinnette bench at about shin level. It obviously has nothibng to do with the fridge that I know of, unless its a light for in the fridge, but it is quite near the hot water heater. I have not tackled getting hot water yet. Could this switch be for that or is it for something else? Its a 2003 Skamper K195.
