I'm curious ... why isn't your RV's refrigerator running while traveling?
FWIW, my DW would never allow our RV's propane refrigerator to NOT BE turned on and cooling continuously whenever there's food in it we intend on eventually eating. This applies except for when fueling up at a gas station - the refrigerator's ignitor circuit gets temporarily turned off for safety while that's happening.
We once owned a 1969 motorhome in which when traveling the wind would sometimes blow out the propane refrigerator's pilot light, but our modern propane RV refrigerator always keeps operating when underway. However, I guess that folks who use a 120V AC residential refrigerator in their rig would need an inverter powering it in order to keep it running while going down the road.
