Thanks for all the kind words! As stated before - I would not do this again. Or maybe I would since I know what to expect - NO!!!
Here are a couple of other pics of the roof from the top side before I put the luan on. Kind of gives an idea of how the wiring is installed. Front is to the left and this is from the top side.
Also, you may have noticed I did not put the speakers back in. I actually ran the wires all the way to the bunk area and they come out by the bed light ports. I plan on putting in some better speakers; not so much for it to be loud but so it sounds better.
I found the issue with the a/c. One of the wires on the ceiling control was loose. Looked ok but it was the temp adjustment side and without current it wouldn't adjust. Now we have nice cold air.
