We've had two Dometics and one Norcold. Really one of each since the first Dometic was 20 years old when we got the coach and stayed troublesome till we replaced it. Replacement was a Dometic 2852. Just a cubic foot or so bigger than 2652, non-adjustable temperature, simple eyebrow panel, etc. People gripe about no temp control, but we were always pleased with its temps. My personal feeling is to go Dometic. For one thing, the doors seem more substantial than Norcold. There also seems to be better parts availability and service information.
Speaking of service, I didn't need help with the 2852 and at least so far with our Norcold N811 and it's out of warranty. But it might be helpful to try to find out where warranty service is available and how tight or liberal they've been.
