The monitor size and location does not interfere with the view of the pavement immediately in front of the coach. The original picture I posted was taken low to show the configuration on the monitor.
This is the correct view from the driver's seat. Looking at the passenger side mirror, the display is several inches below.
If the tasks involved operating the computer are more complex than say turning the wipers on and off or setting and changing the cruse control. Then the monitor is simply rotated to the copilot where the tasks can be carried out.
Wires from under the sink to the dash follow this path..... Hole through floor in sink cabinet, right side of water tank, right side of diesel tank, right wall of generator area, and hole through floor into back of dash area. Included in these wires was a new AC receptacle mounted behind the dash, I taped into one of the kitchen receptacles for power. I used marine grade wire designed for 120VAC from West Marine. All the wires are held in 1.5" plastic flex conduit.
The markings on the rear camera monitor represent the back of the coach. To mark the monitor I placed a long board on the ground across the back where the coach ends and smaller pieces to represent the extreme corners. Then simply traced the boards on the monitor with a sharpie.
