I have one that I put on my new truck. If I forget to put it down or up it costs a lot less than my OEM would. I had a friend have his tailgate stolen years back and it cost him around $800 for a straight tailgate out of a wrecking yard. Then he had to get it painted.
Yes my truck had the backup camera so I lost that function but I also have a cargo camera and it works almost as well as the tailgate camera. I do have to turn it on on my screen to make it work.
Mine is a Handy metal louvered one and looks good on the truck.
