HI. We had a Norcold 1200 in our 2006 Dynasty. We kept the box, which was in great shape, and replaced the refrigeration unit with a 120v HVAC unit from JC Refrigeration. https://jc-refrigeration.com/products/. Did the install ourselves, following written and video instructions. Came out great. The unit gets cold and freezes hard. It only draws 600 watts so it can run off the inverter no problem. We didn't want to change or re-do the cabinetry, so this was a great way to upgrade the refrigeration and keep a good aesthetic.
