Did a simple mod today in my 29RTPR. Removed the 26" TV and mount and moved it to the bedroom

Then I installed a 42" LED backlight TV in its place. This is the mount I used.

First I put the mounting panel on the TV and measured the distance from the the mount to the top of the TV. (6.5 in.) Then I held the mount in place in the TV enclosure and stretched the arm so the center of the mounting panel was centered in the enclosure and measured 7" down from bottom of the cabinet doors to the top of the mount panel for clearance. It worked out that when the mount plate was centered the mount frame was flush with the left wall of the enclosure

Behind the wall there is a piece of 1/2 " plywood glued that provided extra support for the original TV mount, however there is a gap of little over 2" from where it ends and the left wall. I glued a piece of 2X2 to the back of the wall to fill it in. The mount is then held in place with 2 1/2" lag screws. This is what it looks like when finished.

The bottom of the TV just clears the top of the dials on the AM/FM DVD player. My TV frame measures 25 1/4 ' top to bottom, and the TV is 2 1/4" thick.
When the slide rooms are in there is about 1 " clearance between the TV and the back side of the wall. The original tie down strap just fits when it is extended all the way.

This is what it looks like sitiing in the recliner
