I bought this back up camera years ago for using with my work trailer.

It worked great and I could hook up single handed every time.
It is still mounted just above my licence plate....I can switch between 2 cameras.
I bought an additional camera >>>>click here
<<<< and mounted it (hardwired) on the rear of my 5th wheel, on the bottom side of a ladder rung.
I wired it so it powered when I would turn on my (parking/running) lights instead of the back up lights.
This way I can use it while driving to keep track of any rear-blind spots before changing lanes and be aware of close followers.
Also it is very helpful for backing into the camping spots
With a 7 inch color screen the visibility is pretty good, however, it is not the highest of quality...but lasts and works at a reasonable price.
I ran the wire the length of the trailer inside a 1/2 inch pvc pipe chase that I attached to the frame. I used a 2 prong trailer connecter that I have hanging at the rear of the pinbox ready to connect to the wireless sender in the back of my pick-up box.
Because the bulk of the 5th wheel dominates the rearview mirror... I made a plexi-glass bracket that hooks over the rearview mirror...off to the right side ...so I can still use a portion of the rearview mirror focused on the 5th wheel hitch. I use Velcro to attach the camera to the plexi-bracket...easy on easy off, as the power cord is run up near the mirror for access.
hope this helps
