Welcome to the forum. We purchased a wireless camera from Tadibrothers. Installed it on the back of the trailer, works just like a rear view mirror. Being that the distance from the tow vehicle to the rear of the trailer isn't a significant distance, wireless is fine. And their cameras don't use the same frequency as the blue tooth, apparently that can cause bad interference. We chose wireless for the simple reason that we didn't want to have an additional cable to connect/disconnect when connecting/disconnecting the trailer. They offer different configurations, different size monitors, etc. My only suggestion would be to buy a monitor that is bigger than you think you need, lol. We went with 9". We thought that was way over kill, but when viewing the image driving down the road, a larger image is much easier to see when you are only able to glance at it. I don't like the idea of driving 60mph, towing a trailer, and taking my eyes off the road for an extended period to make sure I see what is in the camera behind me.
