Let me add from an experience I had this past week. I had in my head I wanted to do this conversion, also. I happened to pass a Jayco dealer/service shop, so I stopped in and asked the asst mgr his thoughts. He said to stay as far away from disc brakes as possible. Weak link in the system is the electric over hydrolic brake actuator. They are as prone as anything to failure, and if/when it fails, you will be stuck beside the road with no help and no parts anywhere close to get you going. Scared me enough to put the idea clear out of my head. Just my two cents worth. Good Luck!
