Inspired by another user, I decided to work on my own backup camera setup and this is what I ended up with. I may end up buying an extra camera and just leaving it on the trailer but for now I'm going to test this setup for the next couple of trips and see how well it works. I'm not crazy about the license plate mount but for now it'll do.
Backup camera on truck (hitch was off but when it's on I can see it very well and helps in hooking up to trailer):
View from trailer:
Camera on license plate bracket (not a huge fan, but...)
Camera off bracket:
Camera on trailer bumper:
Magnets are very strong and won't budge during transport.
While at campsite, part of the setting up will be moving the camera back onto truck until camp is taken down and we head back home.
