3. Does the CCC2 show a display for BOTH Zones? Or does the AC that is inop has no Zone display?

WRONG!. If you have 3 AC units you have 3 zones. So, if you do not have Zones 1/2/3 showing you have a problem. Usually when you have a 5th wheel, Zone 1 is the Main living room, BUT NOT always the case. ON each AC control board will be DIP switches. So, you flip the DIP switch for Zone 2 on 1 AC and DIP switch 3 for the third AC. Now, as a temp sensor. Ideally you have the remote sensors. BUT, if the CCC2 is located on a wall that will sense the interior temp for that Zone, IT can be a temp sensor and then you only have to run a remote temp sensors for the other zones. I have never seen or even know if you can connect 2 Dometic AC units together on one Zone. IF you do, then you get a COM error on the wall tstat. Since it sees 2 AC control boards. I have 25 years of servicing the Dometic CCC system, ever since it came out. Are you the original owner? YES, all 3 AC units are daisy chained. In my previous post, you would have a COM cable from the 2nd to 3rd AC unit.
