6'4" Bed Differences - 4th gen vs 1500 5th gen

[johnmyster]

I've been looking for a used bed cover for my 4th gen, and have located one for a 2020 1/2 ton locally. The price is right, but not if it doesn't fit.

Did the size of the bed change on the 5th gen 1/2 tons, making it different than the 4th gen HD trucks 2010 to present?

BAK lists two different part numbers, but I'm skeptical I couldn't make it work.

Yes, the 5th gen 1500 bed is different than the 4th gen 1500/2500/3500 / 4.5 gen 2500/3500
