Gene_For what it,sworth, I had the same problem with an overhead squeek, and my coach was ordered without any TV overhead. I fixed it at about the 6,000 mile point by driving along and pushing on things till I found my squeek. I figured out that the plastic headliner was rubbing on the trim strip where it was attached above the passenger side. IF i held the headliner up, the squeek stopped when the headliner was held up, so I installed a single screw to hold the headliner up and the squeek has stopped now for 6,000 more miles. Might work. The board soun ds, could be in the TV cupboard, there are several heavy wires running behind there loose, install a bit of foam to stop them rattling up and down on the metal roof when driving over bumps.
