Attached are pictures of a mod I did to a friend's Motor Home. They are going full time next year (2013). Their old TV went out and they purchased a 32" HD-LG to put in it's place. When the old TV was removed there was a great deal of space for storage. I build a hinged shadow box to hold the new unit. The shadow box is mounted on a piano hinge and has a small skid on the bottom near the slide bolt to take the weight of the TV and shadow box when they are traveling.
I am sorry I didn't get a picture with the TV installed. When the TV is mounted it only protrudes about 2" and covers the opening except for the very bottom. The TV is only 3" deep and sits about 1" into the shadow box. The box is flush with the cabinet when closed.
The interior space was finished off and a shelf added. This added a great deal of storage which will come in handy for full timing. Frank
