To back up what PUCampin said: I bought the $99 Insignia LED/LCD 19" at Best Buy, went across the street to a Radio Shack and carried the TV into the store. The helpful Radio Shack employees went through their selection of plug adapters, found the right one to match up with the TV's plug end, checked the hookup with their 12V supply, and the TV worked perfectly. Now it can be plugged into the 12V power in the RV without any additional wiring or inverters. By the way, it really seems that digital TV signals are more of a pain to find and lock onto than the old analog signals. So much for progress.
