I used a mounting plate without a swing arm for the TV. First I mounted a small plywood square to the swivel about 8x8 inches with multiple wood screws because the swivel is only fiberboard and the mount only uses 4 screws. I then attached the mount to the plywood and it is sturdy. I got a 2 piece mount where one piece stays attached to the TV and the other to the swivel and when I set up, I just hang the Tv on the mount. Yes you can run the TV through the surround. Simply look at the audio out adapter on your Tv, usually an RCA type of plug and go to radio shack or best buy to get an adapter cable that has the Tv style adapter on one end and a standard stereo adapter on the other to plug into the built in music system(this is like the plug for Walkman headphones and there is a port for it on the front of the entertainment unit below the TV). This is nice also because if you have satellite, you can tune to a music channel and turn the outside speakers on to have music outside the RV when grilling, etc. I will try to post some pics for you to see the setup.
