Fly boy, I got an Element Brand tv at Circuit City. It is around 20" instead of the 23 that was there, it is just a better view. I have not mounted it, since I did not want to worry about it shaking in the mount, and wanted more cabinet space. I took out the old tv, and built a box of 1/2 plywood using the dimensions of the opening and the space left in the cabover area. I used the old maple frame that held the old tv 'in place' and inserted a piece of 1/4" birch plywood, and made that into a top hinged door. I included a short 'shelf' at the 'back' of the new box, about 6" from the top, and made a contoured bracket the shape of the rear of the flatscreen, and mounted that in a position where it could bear most of the weight, which is not much. In transit, the tv lays in a pad, on those 2 surfaces, held by bungee cord, and the door is closed. The area under the tv is big enough for a number of blankets or a whole lot of clothes. When we park, I take out the tv, stand it on the base of the 'box' and hold the door up with the bungee. I didn't go into a 'self opening' type of strut because I don't want to encourage any more rattles than I have.
Dunno if I have pix, but I will check.
