I had a 2003 Brave, Model 32V (same as 33V). The cabinet above the vanity was wired for TV - 110VAC, 12VDC, and antenna. I also installed my own 19 inch TV. The only thing that I found was that the signal was weak at the rear TV, so I bought a small Radio Shack TV signal amplifier. It installed inline with the antenna lead, and plugged into the 110VAC outlet. It worked very well. I think that the 110VAC outlet is powered off of the 300 watt inverter, so you can use the TV even when you are dry camping.
Its a shame that the 12VDC outlet is in the back of that cabinet. I modified mine to put a 12VDC outlet down by the vanity.
