There’s only a single coax cable to each TV. What you view is determined by the little button on the coax output box along with the settings on the TV. I’m pretty sure the setup is the same on the Sunseeker 3050 and Forester 3051. The factory installs an HDMI cable from the small compartment ( where the coax cable is located) to the TV and a second HDMI from the radio/DVD system. None to the outside or bedroom TV.
I ran an HDMI cable from the entertainment cabinet to the outside TV. It’s not a hard job at all. That cable goes to a splitter box which takes the output from the AppleTV and sends it to the overhead and outside TVs.
Satellite?...don’t have a clue, don’t have it and don’t want it. Much easier to use DirectTV via cellular WiFi and displayed on the AppleTV.

At some point during every day you suddenly realize nothing else productive is going to happen the rest of that day. For me, it usually occurs around 9 am.
