Might be worth checking the owners manual on the fridge. If your fridge is cold with the truck plugged in, it sounds like a 3-way operation (110V electric, 12V electric, LP). If that is the case, run it on 12V while traveling and avoid the issue of using propane while driving. We had this type for years, but it used a pilot light that had to be manually lit for it to cool on propane.These type of fridges are common in popups and smaller tt's.
As you get into the larger models, the only operation modes are 110V or LP. Then you either turn it off or run propane while driving, and the auto mode controls everything. This is how our new fridge is setup. Dealer said to run it on LP while driving, so we do but it still seems wierd after years of always shutting the tank valves before driving off.
