My newer moho had a 22" tv mounted in the same place, but I wanted to go HD and larger. There is AC and cable in the cabinet above so I ran everything form there, used a Costco swivel mount but kept the back plate that has a Velcro strap for travel. I remounted the swivel with the back plate, new Velcro and have a wireless UVerse box to use when I am docked next to my house. The 26" is the maximum fit when up against the wall without sticking out.
I had to add some cushioning (cork gasket in this case) at some points of the mount because the metal-to-metal was grinding away when driving.
The mount pulls out and swivels, and there is an upgraded audio since we susually watch a movie or other dvd.
