I am not familiar with dual tuner satellite receivers so I can't answer your question directly.
Here's what I did in my '09 Landmark though:
We fed component video and audio over to the bedroom TV. We used a single jacketed cable that had all 5 lines inside it. The cable was fished from the bedroom closet (top shelf) where the receiver was, over to one of the bedroom ceiling speakers, then over to the ceiling mounted TV wall-plate at the bedroom TV.
Using the HDMI output of the same satellite receiver, we fished a long HDMI cable out of the bedroom closet, into the area underneath the dresser, then down into the utility area of the basement. The cable was connected to the back-side of an HDMI pass-through style wall-plate which was mounted on the utility wall next to the antenna/cable wall-plate.
We used RF remotes from Direct TV to control the satellite receiver that was mounted to the top-shelf in the bedroom closet. One remote was kept in the storage basement area with the TV. The TV used was a 26" Jensen LCD mounted on a gray Omni brand swing-out bracket. The wall-mount part of that bracket was mounted to the utility wall an inch or two from the side wall of the RV in order to allow the TV to swing out of the storage area and out into the open. We did reinforce the wall with doubled up 2x4s behind the wall. I think we tied these 2x4s into the floor and ceiling as well as it was a lot of vertical weight to hold.
Best of luck,
Jim
