I crawled under the rig tonight and traced the external hookup to where it goes up into the floor under the bed. Along with all the big power cables from the genset and the shore power. I'll have to remove the bed and see what goes under there. Just for fun I looked in the manual. It shows a really nice fictional wiring diagram where there is a satellite hookup and a router box that is all coax and rca jack connections. It's nothing like what I'm looking at, all HDMI connectors. What I can see is the roof antenna goes into the router and then must go out to the TV's via HDMI.
