I picked up an after market rear view camera and mounted it above the rear plate , and mounted the screen in place of the rear view mirror.
There's an assortment of camera sizes to choose from,, I got the smallest lens to blend in better and have it turned just a bit to view more of the right side of the truck.
I like it so much I got two more to mount some where forward on either side of the truck so as to see whats around me.
All this cost less than the deductable on my insurance should I cause an accident..
P. S. my lens out back is wireless so I tied into my license plate light to power it, I drive with lights on always anyway.
