I just thought I would update this thread, been a while.

We put side view cameras on and LOVE them. Mounted two at the front of the bus, about hip level, one on each door. Then we put a new screen on the A pillar for side view cameras, small one but decent enough to show what was needed. We installed a video system that would merge the left and right views onto one screen and therefore the monitor will display both sides at all times.



Then the nav system can show the rear camera at all times and the A pillar monitor can show the sideview cameras. We also put in a switch on the dash to select which camera to display if we want to only see one large camera view at a time.

Very basic, very useful, very practical!
