I have a Pathway X2 for the living room tv and a Playmaker for the bedroom tv. To get direct connections and bypass the Jayco supplied connection in the wet bay I basically did the same thing but took a little different approach. For the living room tv I removed the radio antenna, since we didn't use it anyway, and replaced it with one of the outside cable connectors. Since it was right behind the tv getting the cable to the Wally was easy. For the bedroom I put the connection inside the bay storage, mounting it just above the 110V outlet on the right side. There is a wire/water line run under the bedroom drawers which made for an easy feed the cable form the connector to the Wally resting on the chest of drawers.
I was afraid to drill any new holes thru the outside as I had no idea what I would hit. I guess I could have asked Jayco. Your installation does look good.
