I finally got around to installing the TV (Samsung 24" "Smart TV"). It was a nice addition to the camper and helped on our recent trip which was full of rainy days.
Still need to clean up the cables with some cable track or a hole in cabinet, but this is what I have so far.
With no Cable, no over-the-air signal, no wifi, we relied on the USB port and "JumpDrive" (USB Flashdrive), as well as cell data (Used sparingly).
NOTE: Few ways we get content on this TV.
1. Digital/standard Over the Air (COAX with Amp turned on)
2. Wifi - SmartTV apps like Netflix etc.
3. USB Flash Drive/stick (Format/convert videos to .MPG4 1366x768)
4. iPhone using Apple A/V Adapter to HDMI port on TV.
