We had the cooling unit on our Norcold 1200 replaced with one of the Amish units (Dutch Aire). We had JC Refrigeration in Shishewana do the work and we also opted for one of the Helium charged units.
Our report -
We Absolutely love it!
With it set at 5 the refer is at 33 -34 degrees and the freezer is at -1 to -4. This was true the whole while we were in Florida for 2 weeks this Oct/Nov and they were having 90+ days.
Glad we did the Amish Unit.
