I just spoke with the service department people and they said the Rockwood had a 3/4" plywood backer in the wall and to use 1 1/2" wood screws for the TV mount. They said that was what they used when they installed a TV mount. Do use decent wood screws, not the black drywall screws that will shear off easily.
