I removed my old TV, the ***** is real heavy and it's on a down hill slant so be very careful. There was a bolt in the back holding the TV in place that when released could have caused some serious hurt, but luckily didn't.
I put in a 39" LED, 1080p that worked out great. It extends outside the cabinet to about 1/2" on either side of the adjoining cabinet doors. The LED is about 2" deep on the inside, so all you see is the screen and frame which is about 1" +/- a little bit from the side.
I installed a fully articulating arm, which is totally not needed so I tightened up the joints so they don't move (I have heard some say they use bungee cords to keep the TV in place when moving, so they can have the articulation arm). The angle of the cabinet works just fine for me and mine.
Having removed a net weight of maybe 150 lbs won't change my MPG because I intend to eat more?
