Refrigerator at high altitude

We live at 4900 ft and regularly camp at 8000+, have never had an issue. Although we do light it before we leave home. Maybe once its running its ok but struggles to light when cold at altitude? (just grasping here)

I've heard a bunch of responses now and and no failures.. And these are folks that camp at these attitudes often.

We have camped quite a bit at elevations in excess of 7000 ft.  Even at the visitor center at RMNP the elevation is 11,796 ft. ,  we  had lunch there in our 177 and the fridge worked fine.  The only time we aren't running propane are those few occasions where electricity is available, otherwise we run our fridge on propane probably 95% of the time and 100% of the time while traveling down the road.  Our 177 is approaching year 8 and has over 25,000 miles on it.  The only issues we have had is when a wasp or bee began building a nest near the orifice.  Since putting a screen over the air flow openings, that problem has been totally eliminated.  The other time is when the tank is changed out and you have to purge the air out of the line, but that takes only about a minute to do.
