The system is in and functional. The pictures tell the story, but I should note that the monitor is held in place entirely with Velcro and can be removed in a few seconds, for those times when you don't need it or you are parked in a questionable area.
The connections are as shown: I turned a wooden plug for the Pollak so that the coax could be installed. Silicone was used to seal what I could. The connector is stainless steel with an o-ring seal, so i hope it doesn't deteriorate anytime soon. I've been upgrading charge wiring, etc. so the main connector is a Pollak 9-pin.
I tried to mount the van rearview camera outside, but there did not seem to be a viable (and reversible) solution, so I made an aluminum bracket and just screwed it to a trim piece on the inside of the tailgate. Snaking the wiring into the tailgate was less of a problem than I had anticipated. When the transmission is in reverse, the system defaults to this camera, but I wired a switch in to enable the trailer camera to be used when in reverse, for campsite backing.
The trailer camera, here nicely decorated with snow, was also attached with an aluminum bracket. The wire came with a useful grommet which made it possible to drill through the hull (shudder) with some expectation that it would not leak (backed up with sealant, however). The wire enters the interior covered by the center trim strip in the
Burro, so that was no problem. It also means that repairs or checks for moisture can be done in seconds. The sole remaining item in this project is to make a small "awning" over the camera to protect it, even though the claim is that it is 100% waterproof.
There is audio to the little speaker on the back of the monitor from the trailer camera. We'll see if it is practical. There seems to be a number of adjustments to the picture and sound, some of which are accessible only through the little remote control. It can also be used to check video from video cameras and the like.
Seems to work well, but the monitor is sensitive to changes in vertical viewing angle, so I may have to tweak the mount for optimal picture angle. The control buttons have a soft blue backlighting which turns on automatically when the ambient
light gets dim. I installed a cutoff switch for the whole system, since the screen has a very faint
light level even when not in use.
First tests have been good, but I think using the screen effectively when driving is going to be an aquired skill.

Someday I would like to hear what all those pins are carrying.
