Hi Dcarr1123,
Some of the UDC setups are as in the attached drawing (from our Landmark). If you have 4 coax connectors in a row, 2 go to the rooftop prewiring and 2 go to the lviing room/bedroom areas. If you have a problem, don't overlook the possibility that the wires got mixed up on the other side of the panel.
Also, when setting up satellite the first time using an outside dish, it's a good idea to hook the wire from the dish straight into the receiver. Get it working that way and then reconnect using the trailer wiring.
