I have a dome dish mounted on the roof of my 3055, it is located over the livingroom/kitchen area behind the main AC unit about 3 feet. I ran the cables forward on the roof to the area between the entry closet and the bathroom. In that area, if you remove the cabinet above the toilet you will find all the wiring that goes to the overhead roof. I drilled a hole up thru that area thru the roof to run my wires down.
I placed the satellite control in the entry closet near the light switches. You should be able to find the satellite coax that would normally go to the docking station in the area from the roof antenna provision in that area also, and not have to worry about finding the provision inside the roof.
Give me a PM if you have more questions.
