I finished this project successfully. I used a rear view mirror camera display for the monitor. Also used a 3 ft piece of conduit and welded some 1/2 angle to the end.  Mounted the pole to the bumper. Drilled a hole in the top of the conduit for the camera.  Wires run under the RV and up through the conduit. I can attach pictures if anyone wants to see them. 

I actually heard from a woman at the shop.  As you probably know, just reaching someone took a few days.  Thanks for the info, I would be willing to drive to Napa at some point if other alternatives don’t work!

I talked to Dean a few weeks ago. If you were going to go to Napa he would make a large window.  Because of the age, there are too many irregularities to make a stock window fit. He isn't big on explanations so he just gave you a No
