[Homer & Marge]

There is only one easy way to get all three and that is to separate and identify each individual run yourself, with a continuity check. My '2012 trailer has two runs from the outside equipment area, one for cable and one for satellite. There is one run from outside awning area cable, one from front bedroom, one from rear bunkhouse. That makes 5. Two are supply and three are tv locations. They are all usually routed to a common area near the central entertainment area (for location of tv #6) If you can, get the mess of cables out of the wall(not an easy task) and identify the three you need. because of all the splitters, amp and cables stuffed through a standard size cutout. the runs you need are: direct sat feed from outside service area. Direct Cable feed from outside service area. feed for over the air antenna from amp. Simple once the cables are identified. Have camped and had all three; sat, cable, antenna, working in minutes. If you need more than one tv for satellite, good luck!! Only direct runs work.
