Good to know. I will have to reach out to RealTruck to see if i can swap it out. Sounds like there are some "solutions" others have figured out to help fix it, but would definitely rather have a product designed right the first time.
I got the X4S, and unfortunately havent been too happy with it. I know that no tonneau is going to be 100% water proof, but there is a major design flaw up by the tailgate. I can see into the bed (if i throw a flashlight in there) when the tonneau is closed through the corners by the tailgate...
