Hi there, just got my first pop up camper. It is a 95 Dutchman Duck, needs a little work but think it be good camper for us. The questions is about our refridge, past owner told me it ran on propane, ...
It is more likely that one knob is for when it is powered by electricity and the other is when it is on propane. But as others have mentioned, knowing the make and model would be of great help.
