Just a word at pre-empting a issue or disaster if you jump too much as it will likely occur as your traveling down the road and your MCD shade drops right in front of you.
My front shade bracket let go while traveling down the road. In this coach the shades fit into six brackets that are screwed into the bulkhead (combo of thin plastic dress covering wood on the bulkhead).
After talking with Entegra CS and getting a fell for how the system was attached. I pulled the shade from the clip brackets (6 of them and requires a screw driver to push back the catch, one at a time to pop the shade out). Found in addition to the two brackets that had come fully off, that all the screws required tightening.
My guess is vibration loosens the screws and once it starts, it is only a matter of time till the bracket pops. For me, I think it is something to check annually. Pop off the shade, tighten the screws and put it back on.
