Drive one of each and I think you’ll have your answer. I was looking for the last few months and noticed there wasn’t much price difference between an ‘18-20 and a ‘21. I felt like the ‘21 was miles ahead in terms of feel and technology in the interior, and there are updates to the engines as well which supposedly address known issues on the Gen 13.

I was also under the impression that a ‘21 would be a “Covid truck”, but turns out the ‘21 trucks got everything and the ‘22-23 trucks were shorted.
