Well folks as mentioned earlier the Seiki in the coach living area was taken out and replaced by the 46 inch Sharp Aquos form the house family room.
First, a picture of the Seiki that was in the coach living area and you can see all of the space around the television. This TV was attached to a couple of metal brackets which were screwed to cabinet grade plywood which was screwed to a couple of pieces of 1/4 particle board. Basically 4 2 inch square head wood pocket screws held this television in place.
The TV removed and plywood repositioned. I did not like the way it felt so off to Lowes I went.
I attached 2 pieces of 1/4 (real wood) for additional support and used about 14 screws reattaching everything. It is not going to move.
