I would contact Jayco engineering and ask them for an a/v wiring diagram for your trailer. Then you can see where the various coax leads go. I have one lead coming into my Designer that feeds two DVR's one of which is in the bedroom. I could hook up the feeds in the basement if I needed two.
You just need to know where the various leads go to and from.
