Congrats on the new 230! We got ours last November and love it, but don't know of any other 230's on the forum. To answer your question, the TV does lift off the bracket, and can be placed on an identical bracket on the awning side of the trailer after unplugging all the connections. There is an outlet to plug in and a cable connection near the bracket. As far as I know there is no provision to connect into the stereo system so the sound is through the TV speakers only.
Enjoy your new baby
