jbcason,
There is a Sony surround system in the front living room, but I am not overly impressed with it, but it is still set on factory defaults and I have not had time to play with the adjustments. On factory settings it is no where near as loud as the unit that was in the 3750. The outside entertainment center is located to the left of the front door. In the picture, it is located inside of the hatch beneath the window. It is a 32" HD tv with a marine type stereo in addition to the television.
Here is a picture from a different rig of what it looks like when it is open:
