I just had a Samsung RF-197 installed to replace my Norcold 1200 which failed completely after 12 years of perfect use. I had mine done professionally by Elite RV Remodeling and Repair in Harrisburg, OR. There are multiple threads on this forum which deal with this issue. The most common commercial refrig in these threads is the Samsung that I bought. There is a very long and detailed thread started by Bob Nodine, and I had one about a week ago that dealt with the failure, cost, and possible people to do the work. There are others on here also. Simply use the search capability on the Monaco page for "Norcold". Having it done professionally cost me a little less than $3,000. People who do it themselves spend between $1,000 and $1,500 for the Samsung. It was recently on sale by Home depot for about $1100.
I have been using my Samsung now for about two weeks and so far, it has been delightful and I have no complaints. My installers also checked my alternator to ensure that it is putting out full output (so that it can supply all power needs going down the highway) and you turn on the inverter and run the inverter all the time which then powers your residential refrigerator when driving down the road.
Good luck If you want any specific information, email me direct.
