The cables for a Trav'ler installation are NEVER there unless the coach manufacturer specifically said it is wired for a Winegard Trav'ler. Satellite Ready means IT IS NOT wired for a Trav'ler. If it's wired for a dome that usually means 1-2 coax cables and a 12V power supply. The Trav'ler requires its own 6-wire control cable that will not be there. Sometime Winnebago "satellite ready" setup means there is a place where you can drill a hole and run the cables to the place 1 satellite receiver is expected to be installed. If that's the case it would not be so bad unless you plan to use more than 1 hard wired receiver.
