I have a 2002 Winsor which has a similar situation.
In my front overhead cabinets I have a switching device that all cables hook to along with the front and rear TV's This enables me to switch from Cable, Antenna, Satellite, or VCR for either the front or rear TV.
If you have 2 TV's I would suspect that you would also have such a device. By having this RV manufacturers can route all incoming cables to 1 location and then a cable to each of the TV's.
