Thank you everyone for all of your information and thoughts. This really helps a green horn on solar and DC compressor fridges.
I do have a couple of Dometic portable DC compressors fridges already and really like them. I bought them because of the problems with my Norcold. One I well still carry as it is a smaller one and well be used for drinks (have to keep the adult beverages cold, very cold). I know when I plugged my first one I bought I was really impressed with how quickly it cooled down. I could feel the difference in a matter of minutes. I have a CF 035 and a CF 025 and really like both of them. When I was experiencing the worst problems with our Norcold we used the 35 for a freezer and the 25 for a fridge. Worked out really well. I bought ice for the Norcold and placed the ice in zip lock bags and placed them into the Norcold to try and cool it back down.
Alex,
I viewed you excellent installation post of your DC fridge install when you posted it. I got a lot of information from your install.
