I been thinking of doing the same thing, I also have a Prevost H3-45. I lived in Vegas, Just about finishing my Prevost conversion. Bob we have a lot in common. Good plan you have.
I found you can get double Din Radio or head unit that can support up to 3 or 4 camera. I was thinking good option for Vanlife oR RV as it is one less devcie you need to buy/manage. You can even install a second LCD Display somewhere to view cams.
I bought a 2010 Horton, much like yours.. and of course got no spec sheet info for anything on the vehicle. Do you know how I would go about getting the original build specs and wiring diagrams? I appreciate all you have posted on your build .. it all helps me!
