Mine used to be really bad in cross winds. Then I noticed that my passenger side view mirror was loose and wasn't sealing correctly. The dealer replaced the whole mirror assembly, now it's not as bad, but still occurs if the cross wind hits it just right. I just live with it. Life is too short to stress out about it. It is what it is.
Kind of off topic but, frankly, I don't think these trucks are any quieter inside than any other vehicles that I've owned. I know a lot of reviews state how "eerily quiet" they are..I don't know, I think it's about the same as any other truck I've ever been in. I drove two RAMS before I bought mine, and I also had one as a rental, and they were all the same. Not bad, but not luxury car quiet by any means. The ANC works great when the truck is not in motion. Start driving down the highway, and I hear wind noise, not leaking - just noise. It used to drive me crazy, now I just ignore it and turn the radio up.
