I have a 2005 Conquest Super C, with the "Entertainment Center" in the overhead. I too am looking to convert it to a sleep area, moving the TV on an articulating mount in right hand corner (like some of the newer models have). This way I can replace the sleeper "sofa" (loveseat) with a reclining loveseat. Looks like it would be pretty easy to do.
Originally thought the Entertainment Center would be the way to go, seeing that we would hardly need the extra sleep area. But after spending time in it, we found the original TV spot was not ideal (partial blocked when viewing from sofa), and the sofa was uncomfortable.
