Hello. Wondering if anyone has a suggested roll up tonneau cover for a 5'7" bed (no Rambox). I took the Mopar soft trifold off of my 2021 ram and put on my new - but it doesn't create a waterproof seal on the side rails and the bed is always wet and virtually useless. Also has anyone else noticed the large gaps between the back sides of the truck where the tailgate meets? No way to keep water out of there either even with aftermarket whether seals.
