Here is how mine and a friend's Montanas (different floor plans) worked. There was a metal plate screwed to the bottom of the TV. And another metal plate screwed inside the bottom of the cabinet. The plate on the TV slides into the plate in the cabinet and latches. You had to reach behind the TV, lift a spring catch, and slide the TV out. On mine, there was an opening covered by a plastic panel in the toilet room behind the TV. On my friends, there was an opening in the side wall of the pantry covered by a similar plastic beside the TV. Look around the TV cabinet for similar openings.
