JALSBERG......Just keep hunting.....I was in the same situation with my Monaco. Make sure you post on the Country Coach Forum. Almost all of the radiators were built by someone else. When I looked for mine, I kept getting directed to a place in Sacramento California that made radiators. They wanted almost $3000.00 ( I thought this was ridiculous). I just kept posting at different sites and a guy on the Monaco site linked me to a surplus yard in Indiana. It just so happened that he bought out about 20 units of Monaco radiator assemblies. They were brand new 2009 units that were assembled with radiator, charge air cooler, shroud, frame and trans cooler. They were $695.00 with $125.00 for shipping. I was able to install this brand new unit which included a newer/better design.
What I learned from this was, one....keep looking and two.....they used the same radiator and assembly from about 2005 through 2011 on Monaco products. So take good measurements and start looking for other year models. I'm sure someone bought some radiators when Country Coach closed their doors. Country Coach is now open again selling parts and doing service.....maybe they would connect you to the manufacturer or be reasonable on a new one.
