Cherokee 274RK tv hookup

[rotaxtwin]

I have a 2018 Cherokee 274RK and I can't figure out how I'm supposed to connect the tv outside. There is a coax fitting and a single composite video cable connector on the door side of the camper and a single coax cable on the opposite side. My question is is the coax on the door side connected to the roof antenna and what is the purpose of the single composite video connector that's there, as there's no red and white audio out there. And where is the source side, if the outside tv is the receiving end? And what is that coax on the other side of camper. I pulled the radio and there is only one set of composite outputs connected to the wall plate in the cabinet above the fireplace. The 2nd composite output is not connected to anything. I tried to get a wiring diagram but struck out. Any help is appreciated.

The coax on the drivers side of the trailer should be the cable / satellite "in" access.

The coax on the curb side of the trailer should be the cable / satellite / antenna out to the tv.

There should be a small box inside usually near the main tv location with a small switch to change from cable to antenna.

No idea what a composite output is, Picture?

What the OP calls a composite video connector is what the rest of the world calls an "RCA jack." One of the common places you used to see these was in a three signal yellow/red/white cable set, where yellow was composite video, and red and white were left/right channel stereo audio.

If there's just one jack, it might be mono audio coming from the entertainment center, not video. I always say, "If you haven't put your oscilloscope on it, don't guess what it is."

But you can actually detect the audio with an AC voltmeter or multimeter on the AC scale. Put on some music with a loud beat and you can actually see the needle on an an analog meter swing with the beat.
