SoundGuy, I recall seeing your fan solution in your gallery sometime in the past. Good workaround for the lack of a vent.
Skimping on RV manufacturing has been taken to a high art form, so maybe that's why we do so many mods!
I had a phone conversation earlier today with an "experienced" tech at our dealer. (Though I requested someone who was directly familiar with our model, that did not happen.) After stating my intent his answer, though well intentioned, was filled with way too many words like "probably," "should be," etc. in responding to my question about a hole in the ceiling above that hollow panel we have spoken of. He did give me the name and number of someone at Coachmen who might know the answer. We'll see.
Sooo, I may not want to mess with disassembling that part of the cabinet before we head out again this weekend. Too much else to do this week other than RV stuff!
