Possible Fridge igniter problems?
Did you try resetting the fridge once you got to the campground? I'm assuming you checked and your propane tank was on. It's possible your flame went out while driving own the road and the fridge was unable to relight due to the airflow, which is why you want to test at the campground.
May want to try cleaning the burner, spiders love to make nests in there.
