Thanks to everyone who posted. The answer is that there is a single RCA plug just to the left of the coax cable hookups under the entertainment system. When I first looked at the RCA plug, I thought it was another coax... but upon closer inspection it really is an RCA recepticle. I plugged an RCA male end into this plug and the other end into my TV and
I had video. As previously stated, the audio goes through the camper speakers... (which is why there is only one RCA cord required).
May I respectfully suggest to Forest River that they add this information to the users manual that comes with the camper.
