I really do wonder if the air syphon or cooling air column is sufficiently narrow and sufficiently sealed off from other areas to actually work? I have a lower access/air vent and an upper exhaust vent which is about two feet higher on the side of the trailer. Perhaps build a better "chimney" and add a couple DC muffin fans? My quest for alternatives has led me back to my upright Coleman ice chest in the interim.

Jack I suspect that the money spent on an temp alternative cooler may be better spent having the fridge system you have checked and cleaned by an rv repair place.

Over Labor Day weekend, I picked up a Black&Decker 2.7 Cu.Ft. compressor fridge from ChinaMart. 79$. I believe it is a rebadged Haier. Fired it up on shore power in the trailer; ice cubes in 3 hrs. Also could make a heck of a room heater in chilly fringe season adventures.

Well, it fits under the table of the front dinette so will serve while on the grid until I get a sheet metal chimney, baffle, and muffin fans behind the Dometic. I don't have a sheet metal brake so will have to get my sketches and method of install firmed up before borrowing one.
