Here is an easy way to get video up front while on the road.
Grab one of the video outputs from your head unit (there are two available) and feed it into your camera control box.
The control box (multiplexer) only has three inputs (left/right and rear camera). You have to chose which one you don't need. I personally don't use either left/right cameras so no big deal to me. You need an adapter cable available from the manufacturer.

Now to figure out how to get the TVs in the bunk beds to work without having to fire up the generator while on the road.
I pulled one off and they are 12v LCDs. I thought they were 110 since they are plugged into 110 outlets, but there is a transformer hidden behind a panel. Not sure why they didn't just wired them off of 12v. Need to find out how to run a set of wires to them.
