Is there any evidence that later build dates are more problem-free than earlier build dates?

There are always growing pains with a redesign. Nothing unique about this one. You'll have recalls the first year, which either won't apply or will have been taken care of in the second model year. Some of the more significant TSB's may be addressed, but I suspect you'll still have those issues 3 or 4 years into it. I seriously doubt there's any real data on this for 5th gen Ram trucks though, at least nothing that the general public would have access to.

True, normally I would never buy the first year of a new design. But I did it twice in a row, with my 2015 F150 and now my 2019 RAM. My F150 was flawless for 4 years. My RAM is only about 7 months old, but also flawless.

Smoothest drivetrain I've ever owned on any truck for sure. That being said, I am keeping an eye out on the rear window leak, which seems to be stemming from the same vendor that's giving the new generation GM trucks rear window leaks as well. Lucky for Ford they use a completely different design and vendor.

My 5th gen has had the CHMSL leak and was repaired by the dealer. July 2018 build.

Sorry to hear. That's a bummer for sure.

I doubt it. My truck is a March 2018 build, and I‘ve had some minor issues like brake squeal and a few recalls, but none of the more egregious problems like water leaks, clunks, or rear bezel cracks, so there goes that theory

June 2018 build and same for me.
