Just setup my Dish on my 2014 "Keystone" 5th wheel. Keystone now runs a coax from the living-room tv area to the bed-room tv area. I have the living-room tv hooked to the sat box via HDMI. The bed-room connected to the sat box via coax to a A/B switch then coax to the tv and the tv set on channel 4 (you can use 3 or 4). The A/B (A=antenna, B=sat Box) switch allows me to watch one tv on sat and one on antenna if I wanted to.
Of course if both tv's are on sat, they must watch the same channel and I have to change channels in the living-room.
I would think new Forest Rivers have a similar setup...
