Cover that doesn't sit high on 2nd gen tailgate

I got a Truxedo Lo Pro and am pretty pleased with it but I learned what others have known. The 2nd get tailgate top sits low and creates a nice gap. I took out my tie down cleats and bolted the rails as low as they could go but it didn't help much.

You can see enough of a gap you can see the bottom of the release latch at the right angle. I'm debating adding some weather stripping there to keep water and prying eyes out but figured I would ask if anyone has any tips or knows of any covers that are known to accommodate for the tailgate on these trucks. Thanks!
