We have a Supersonic TV that came installed in the TT. Didn't think much of it at first, but after plugging the sound into the cd/radio and we like it better. The sound of the tv's speakers was absolutely horrible. Adjustments made no difference. The picture is quite good especially on ota digital hd signals and blue ray. It does a good job on non-hd directv. Amazon sells these. We've never run it on anything but 12v, shore power or not. Our 2 group 27 batteries and solar can get us through a weekend of dry camping.
