So I've been to my dealer twice about this and the can't answer my questions. I have a 2020 GMC 3500 AT4 with the 6'9" bed. I was looking at buying the GMC (associated industries) hard folding tonneau cover.
I'm wondering if, when folded up, does it block the camera mounted in the 3rd break light. I know Extang ones do block it.
Also, when the dealer parts guy printed instructions for it, it said you had to drill multiple places to attach the bed rails.
Just looking for answers from someone who has one. Thanks
