I spent a lot of time on this issue several years ago. The issue seemed to be caused more by the top of the chimney than the door at the back of the fridge. An air deflector in front of the chimney on the roof was the final solution. A furnace air filter taped to the inside of the rear door solved it about 80% - 90% without impacting cooling much. But every camper design is different, with different airflow patterns, so YMMV.
so I wonder if I just tape the front facing opening up top and see what happens if that would be good enough for a test. then if it works build a deflector or somthing more permenant that would only divert air while I am moving. I just find it weird that it only seams to happen when I am driving in gusty side winds or a rig passes the other way, but I can do 100kph in the mountians on a calm day and it stays going... or in the summe rwhen it is hot and the flame is at a higher setting it rarely blows out.
