Never had a Norcold anything so I don't know anything about them. I've had numerous Dometic refrigerators over the years and can truly say they I am not happy with the way they operate. They have a tendency to not handle high ambient temperatures well at all and frequently will allow the inside temperatures to rise to the high 40s or low 50s degree Fahrenheit. This is a very dangerous area for holding potentially hazardous food. As badly as these refrigerators function, the customer support from Dometic is much worse. Actually almost nonexistent. When you do actually get ahold of a company rep on the phone they tend to be rude and very condescending.
