Mystery switch

[TNTraveler]

Have a little rocker switch on RH side of Cabinet on drivers side. Can anyone tell me what it is used for. Tried various items but no luck. Also since ever one in this topic section have Cummings diesel engines have any one put in a Banks system or thought of putting one in? Also what is your current mileage, mine is getting 10 mpg and think I could do better.

Could it possible be the switch for your water heater to switch it over from propane to electric?

Thanks for the reply. But no, have switch for propane on hood over stove and also switch with light below cabinet above table that is for electric.
