I have a feeling you are having a problem with the input shaft to the PTO. Country Coach did not use a lube feed to the PTO drive shaft so they end up beating themselves to death. Google PTO shaft failure on COuntry Coach and you will see all sorts of information. Here is one of them:

Good luck to you. There is a kit available to add trans lube to your PTO. I would advise doing it. I have the same PTO in my Panther but it has the extra lube line. Made sure of that before I bought the motorhome.
