I run a 22" NAXA 2207 dual power LED HDTV (120VAC / 12 VDC) in my TT ($160 to $180 via Amazon). If I am just watching TV, I plug the TV into the cigarette lighter port (the one with the antenna amplifier button). I use the Wineguard digital antenna and it works terrific (about 60 Watt power draw for the TV alone). My older (2004) TT has a surround sound DVD/AM/FM system that draws 160 Watts and is only 120VAC power.
When I want to watch a DVD movie without running my generator, I plug both the TV (120VAC) and the DVD player into a WAGAN 400 Watt inverter ($40 via Amazon) that plugs into the TV cigarette lighter port. This works perfectly!!! (and no interference from A/C or furnace).
Guess What!!! It is a modified sine wave inverter....so that blows that PSW theory...at least for my setup (PSW is actually recommended for 60 hz motors and such and "some" TVs. Like I said.... Works great for boondocking whether or not I want to run the noisy generator. I am running two series 27 marine deep cycle batteries... Watched movies all night the other night (well, at least the kids did), with barely a drain on the batteries. HTH!! I highly recommend the NAXA AC/DC TV and the WAGAN inverter..... it also has two USB ports for charging cell phones, Ipads, etc.
Oh, and I also use a Solar panel battery charger, so I rarely need to run my generator when boondocking.
