My two cents... got this for our X19H...

Got it at CostCo for $150, so shop around. This is not a "smart" TV but it will play digital files through a USB connection (feature called ConnectShare from Samsung). I simply have a small portable Hard Drive with about 300 movies in digital format (MP4) and it plays off of that. It's small enough (the HD) to velcro it to the back of the screen so it's out of the way. Great for those rainy days in the camper...
I also used the RCA connectors that JayCo ran to that area from the head unit and connected them to the audio out on the TV. These were run to get DVD video to the screen. I then removed the head unit and swapped the RCA connection from Video Out to the Audio IN on the head unit. Doing this, the audio from the TV now plays through the ceiling speakers. I found this to sound better (may upgrade them later though).
Hope this was helpful....
