What was the resolution?
I had some similar issues and here are a few things to try.Did I install BAK X4S incorrectly? The directions say to align the vinyl cover with the front of the bed but if I do that then there is a large gap at the tailgate. So I did my best to align the tail since I the flappy part at the front covers just fine. Also, I could not get it to be perfectly even, maybe a manufacturing issue (truck or cover). Also, the little metal bed bumper that aligns the cover rails sits quite high - less than half of it actually touches the front of the bed (the part that makes it look like its fully touching is the foam weather stripping that comes with the X4S).
The resolution is that our instruction sheet could be a little more clear. There's a step that says to align the front edge of the cover with the front edge of the rail, but it doesn't indicate that it's a temporary positioning, like a starting point for alignment. Later it does say to push the cover to the tailgate, so that the seal makes contact, but I can see where that could cause confusion.
Nice!The resolution is that our instruction sheet could be a little more clear.

We worked through the steps in the DM's. The cover is installed correctly, the seals are making contact where they should, and the cover is working perfectly! I also sent the feedback to our product team and engineering department.

I know that most people aren't expecting a hermetic seal, especially at a point where both the tailgate and the cover open and close against it. I think this illustration out of the Revolver instruction sheet shows what the engineers were going for. In my experience, you have to place a seal where it doesn't receive abrasive wear so that it gets damaged over time, or comes off. Hope that's helpful!I'm having the same issue with my BAK X4S where the cover does not cover the tailgate enough, leaving a trough to collect water. I have been looking at h shaped gaskets to attach to tonneau top and having the top of the h cover the gap on the tailgate.
I installed it correctly. No resolution. This is just how the BAK X4S fits a 2025 RR.
It fits perfectly, leaks very little, and has been fantastic so far. Very, very, versatile!!!Realtruck rep on here helped me get my sentry ct for my 2026 RRaptor. It fits great!
