PianoTuna is correct that the residential type fridge are a lot cheaper and that is why they are installing them on some of the new coaches, to save money. But at the same time they have to install a pure sine inverter and six house batteries to keep that residential type fridge running.
I have never had any problems with my Norcold 1200 LRIM in nine years that I have had my coach. I set it at six and it stays at 34 degrees. And I imagine the freezer is much colder. The ice cream stays pretty solid.
I really like where you can use propane and AC current. So if I ever have problems I will buy the Amish made coils. It would be too much of a problem removing the one piece windshield to bring in the residential fridge and removing the Norcold, plus they never are the perfect fit. So you would have to hire a carpenter to make modifications so that it does not look like a shoddy job. Just too much trouble for me.
