Running your propane Refrigerators while traveling?

I don't know why people continue to refer to the refrigerators as having an open flame. This is a total fallacy. There is no open flame. If there was an open flame it would blow out going down the road due to the large amount of draft that would be created by the trailer moving down the road rendering the refrigerator inoperable. The flame is contained within the confines of a small sheet metal box built to shield it from blowing out and keep it from igniting anything inside the rear refrigerator compartment.
