Here's info from my experience on my 2000 Affinity, 42' tag axle, C12. If birdhunter or anyone can share details on their Duralite that would be awesome too.
Part of my research last year I called Duralite directly. They were very helpful, gave me a part number, but said they don't make that part # anymore. Said Colton might have one in stock. I talked with Colton for several days and emailed drawings back and forth but none of us could get comfortable with exactly which part # was needed. Colton had all the Duralite design prints, and we could easily tell that the part number Duralite originally gave me wasn't correct.
I talked briefly w/ CJG, but couldn't get totally comfortable with them either.
Talked with Kevin Waite, who talked w/ Radiator Supply House. Even after providing them pictures, part numbers, and measurements, they still sent me the wrong unit initially. They got the correct one built and shipped within two weeks the second time. First one took 3-4 weeks. Total cost with shipping was around $2500. The correct RSH part number was 5681 (RSH-5681-CAC).
This was for my 42' tag axle chassis. I don't know if the 40' single axle is identical or not. What I gathered from talking to a few folks is that Country Coach used oversized radiator and CAC, so it was more unique that what other similar coaches used.
Main challenge I noted that should be watched if you have one made.... the original CAC was a molded intake port and tank, which had a rounded corner. The RSH replacement is welded plates, so much more square. Fitting that "square" corner up in the space behind the tag axle was really tight fit. (Reminds me I need to check it at some point and make sure nothing is rubbing.)
Attached should be a .pdf file of what I measured once I got the original CAC off the coach. I did my own removal/installation. Not the hardest, not the easiest. Mostly heavy, awkward lifting of all the different cooling components that fit together. I started making notes of the process, but I think that fell by the wayside at some point. I didn't remove the radiator, just loosened everything, lowered the oil cooler, and pulled the CAC out the side. Several posts from other DIY owners gave good pictures and pointers that I referenced.
I still have the old one. Big crack in one of the tank sections. I'm assuming I should sell it for the price of scrap metal, but haven't made time to figure that out. Could theoretically be repaired, but I decided it wasn't worth the risk of just getting another failure on 20 year old aluminum joints.
