Most modern TVs have multiple input capability. Hopefully a coax input for the batwing or cable TV. I would set up everything else for HDMI. For sat install coax to storage locker with a bullet connector. And HDMI from the controller to the TV. Use HDMI splitters for remote TVs as required.
I've always routed wiring unseen - ceiling, walls, storage areas and look for inside water routing that keeps water from freezing in the winter.
My sat box uses a RF remote which means it can be mounted out of sight. Many RV cabinets like mine have depth exceeding equipment depth. Mine is mounted vertically on a cabinet back that has adequate air circulation. My RF remote also has IR for basic TV control.
