I have a 2007 Daybreak 3270. On mine there was a dummy vent cover on the roof and when you take the cap off there is a sticker that says satellite cable here. You use a 1 1/2" hole saw and drill though the rubber roof and plywood. Be careful you only drill the rubber and plywood and don't go into the foam or you can cut the cable. That cable runs up front to the audio video switcher. On mine its on the right hand side. If you call Thor Motors in Wakarusa, In. they should be able to tell you where on the roof the cable is located. Most installer will just drill a hole through the roof into the cabinet your controller is in and they use a plate over the cable on the roof to seal it. Hope this helps.
