This was my first MOD to my TT. Since my kids get up at 6:30 every morning (even when we are camping) this buys my wife and I an extra hour of sleep. It then stays off for the rest of the day.
I take it down when traveling. The Apple TV is attached to the wall using velcro so it comes down easy. 1 screw holds the tv on the wall mount. What's nice is that we don't have to carry DVD's with us. All the movies are on my iPad and I can just broadcast them using AirPlay.
