pickuphunt,
I posted this last year when I installed the TracVision 4.............
I have a 3600RL purchased in Aug 06. When I bought the unit, Clovis RV was to install the tracvision 4. After drilling two holes in the roof in the wrong location, I told them to stop. I installed the unit myself and didn't attempt to locate the coax in the roof. When the units are assembled at the factory the coax is coiled up in the roof (somewhere). Good luck drilling a 3/4" hole that is required to feed the wiring to the satellite dish and retrieve the cable at the same time. I drilled a 3/4" hole over the master bedroom cabinets and pulled the wiring. I was able to pull 12 volts and coax through the cabinets from the 12 volt outlet in the tv cabinet. I mounted the satellite control in the blank space between the upper cabinet doors. I used the existing antenna coax to feed the living room tv. All wiring is concealed inside the upper cabinets. With the use of 3 AB switches, I now have the option of park cable, roof satellite, antenna, and/or remote satillite to both tv's at the same time.
