I have one on my 2019. They are made by a company out of Michigan called Fold-A-Cover, which was an OEM supplier for both RAM and GM. Unfortunately they went under last year during the COVID shutdown. I had one on my last truck that was over 15 years old and still worked like a champ and looked new. They have one huge advantage that I like that many might consider a disadvantage. They fit on top of the bed rails so you don't loose any width in your bed. Many people like the clean flush look of the other covers, but to me I didn't want to lose any space. If you decide to purchase one of the remaining ones know that the bed rail attachment is a separate piece that must be ordered along with the cover. They are in extremely short supply, I had to have a person run a list of the remaining ones in stock around the country and then make calls from there to find it. The covers are in more plentiful supply, but it's worthless without the rails so shop accordingly if you decide to get one. The internet will show in stock everywhere but they are not, so don't believe what you see without calling to verify. The rail kit for a 6'4" bed is 82211301, and the cover is 82211298.
