If no one else needs a cable box you shouldn't need one either. Run the wire straight to one tv from the post and that will bypass any the wrong in your camper.
I didn't know there was room for 4 TV's in a class C. All with something different on?
You need to start by connecting a working campground cable connection directly from the power pole to the back on one of your TV's. If you can get that TV to work then you know you have a good working signal and you have the TV setup properly. You would then take that same cable and connect is directly to the back of the wall plate that you turn on and off to make the switch between OTA TV and Cable TV. Disconnect the coax labeled Cable on the back of that plate and plug the same direct run coax cable into that port. Ensure the power button on the front is off and go to each TV and repeat the setup routine. If that works then you need to reconnect the coax connection in the wall plate and take the cable outside and connect it to the connection in the wet bay or outside that's labeled Cable (not Satellite or Aux or anything else) and repeat the process. If you now do not have a signal then you know you are either plugged into the wrong connection or your dealer lied to you and there is an issue with the cabling between the outside connection and the interior wall plate.
