Norcold 1210 with replacement cooling unit propane blows out on the road

I have the same issue with my older one, it is one you have to hold the button down till it is going, then if you get a gust of wind you have to push the button down till it re-lights.  people have built baffels, taped up a bunch of the vents in the lower cover to preven gusts from entering, or instaled furnace filter material on the inside of the cover to difuse wind gusts.  I usaly get it when I am traveling over 50mph and a big truck goes by in the opposit direction.  I keep intending on trying to make some sort of baffel maybe this year.
