There are three cables connecting the TV to the rig:
1. A 15 ft. HDML cable sending HD signals from our satellite receiver.
2. A 110 Volt cable from the inverter.
3. A conventional video cable from the roof antenna.
All originate behind the TV control panel in the right front cabinet. The cables are routed behind (actually under) the shallow cabinet above the right passenger window. (The innards of this cabinet are made of cardboard, and are easily removed and reinstalled.) From there they go above the entry door to the structure I built to old the flat screen. I had to drill a 3/4 inch hole above the door into the side cabinet. This was hidden by a strip of maple that I mounted on top of the door. See picture:
One advantage of the HTML cable is that its plugs are small enough to go through relatively small holes.
Hope this helps
