The question regarding Country Coach and OTr depends on which year. The new 2006 and 2007 are apparently OTR. But , I still see a Unit on the roof so I am not sure. The older CC's had roof Air.
There have been long debates regarding OTR air so you should read up on previous posts regarding the Pro's and Con's. My Coach is OTR and keeps us very Cool when traveling in hot climates. I have a variable speed control to adjust fan speed, and its quieter than roof air units.
Country Coach is a good Coach.
