I currently have my third truck camper—a Lance 1172. I’ve had this camper 3 years. I have an issue, sometimes, where the propane supply to my refrigerator is lost when we move from one campground to the next—this might be a 200 mile move or a400 mile move. When I get to my new destination or go into the camper an hour or two into the drive, the fridge is beeping and has lost the propane connection. Once I turn the fridge off and back on, it reconnects and will run without issue if I am parked for days. However it may do this several days in a row or sporadically if traveling. Any ideas?
