When I purchased my 2018 Denali I did a lot of research on bed covers. I looked at many covers that were installed on other trucks. In the end I went with the ReTrax Aluminum non power
and have never regretted it. For the most part it is dust and water tight. It locks in any position and when closed and locked I believe it is the most secure cover out there. I have a Pullrite Superglide 5th wheel hitch and the Retrax slides right over the top of it making the bed completely secure while disconnected from the trailer.
