If you have a dome you won't have HDTV. I would think that your coach should have a something like a Winegard video distribution box in your overhead. The output from your Directv box should be connected to the Sat In on the distribution box. Coax cables should already be in place and hooked up to the Main TV - Sat Out and Second TV - Sat Out
My Video distribution box allows me to feed front and rear TV's from ANY input source including RV Park cable, my DirctTV from the dome, or the crank-up antenna. I can chose either one or both TV's BUT, with only one DirecTV box I can only view the same channel on both TV's. With either the RV Park cable, or the crank-up antenna, I can view different channels on each TV.
