Yes mine is in a Dometic 7 cu foot in my 2014 23D. Thanks for the kind words, but I made mine also. Simple 2x3 aluminum extruded tube milled to make an air duct. Two 60mm fans inside pull air into the duct and blows it out the holes in the back of the duct. Blowing the air through the cooling fins in the back of the fridge. A 3 amp breaker two 2x3 plastic end caps and a power switch complete the project. I’ve been using mine for about 3 years now and it helps keep fridge temps low and I never have problems with icing up. 12volt power was obtained by running the 12 volt
positive lead out through the drain tube and the ground is attached to one of the cooling fin screws via a eye crimp.
There is a guy now making them and selling them online called “fridge-fix”
