Hey Adam! You have the exact same configuration I’m considering installing on my 2020 Silverado 1500 TB - Leer XR with headliner, rack rails, etc. I’ve been reading a lot about this model on the newer style Silverados and came across one thread that pointed out a potential flaw in the design where the cab meets the cap. This poster pointed our the height difference, and due to the slightly higher cap height, it captures a ton of wind noise. Again, this is what the poster claimed Was curious if you’ve had any issues like this. It makes sense if you look at side photos, you can see that the shell cap height is a little bit higher.
In any case, wondering if you’ve had any similar issues to this. For what it’s worth, it looks great! Thanks in advance!
