Has anyone added a window behind the TV? We are thinking of adding a televator to lower the TV behind the fireplace. This would give us more counter space when the TV is down. Also thinking of adding a picture window behind the TV. This way when the TV is down we can see out that side of the trailer. The televator seems fairly straight forwards as there is lots of unused space behind the fireplace. I'm interested in what it takes to add the window? Any advise would be appreciated.
