Good question, as I am in the same position. Replaced the Norcold with a residential Frigidare model. The cooling unit itself failed again on the Norcold but was still under warranty and it was promptly replaced and I installed it on the 1200 once I got it out of the RV. Now have the Norcold up and running in my garage and it seems to be working great. I want to put it on Craigslist as well but not sure what to ask. The new cooling unit itself is just a little over $1000.00.
