Just an FYI on Leon. He can do warranty work on both Norcold and Dometic. When he replaced our cooling unit on our 1200 series, he gave us a 3-year warranty. It is his own design and he is Amish, but it is not actually the one sold as "The Amish Cooling Unit." In fact, his is a bit different and he will tell you why his is the one you want.
He also sells and installs the ARP unit, which is a fail safe switch that will shut off your fridge when the system is getting overheated. That happens when you are out of level. It shuts down the fridge, then restarts when it cools down. Keeps them from burning up.
