There must be a separate cable somewhere in the coach. How many inputs do you have at the outside? Satellite requires a dedicated cable to/from the receiver.
Yes, once you find the dedicated coax line to the inside of the coach, you connect to the satellite receiver and then connect HDMI to the TV. No, you won't be able to watch satellite in the bedroom unless the satellite receiver has RF output (ie: channel 3) as well as HDMI.
You can test the cable to see if it's the right one by connecting a 9V battery to one end and checking to see which cable you get 9V from on the other end.
