what brand is your in-motion dome? We have a TracStar SV360 on our 2004 diesel pusher and it's still working great. We have had to replace a few parts the tech said that it is much better made than today's models. I would try it to see if it works and if you don't care about HD, order a basic receiver from DirecTV and a package. We don't care if we have HD or not if we have TV. When we had a home, we got HD "local" channels using an analog-digital converter box. Now that we full time, we subscribed to affiliate feeds for ABC, CBS, NBC etc. If you are anywhere near Houston, call Dave at Sats2Go. He's the RV satellite "guru" in our opinion. We drive from Florida to have him work on our satellite system. He added a switch so we could have a separate satellite receiver in the bedroom so we could watch a different channel there. He can order the receiver for you and install it.
