installed the fridge
in this year model and then built the rest of the trailer around it. Good for them, bad for anyone with a Casita
built before 2003. I was in contact with the factory and they recommended taking the cooling unit off and passing the frig through a window. It turns out, the later models allow doing this but the earlier models have no window large enough to pass the frig through.
So, after considering cutting into the fiberglass or installing a larger window, I finally decided to modify the frig instead. I cut a chunk out of the frig making it possible to pass through the trailer door. You can view my frig modification on this page of my web site. Refrigerator, Casita
If you are ever in a position to replace your own frig, let me know and I can give you a helping word or three, as needed. In another words, tech support.
