Actually we do carry a toolbox specifically designed to fit the BAKFlip MX4 tonneau cover, part # BAK48121, on your 2018 GMC Sierra 1500 with the 6-1/2 foot bed. It's the BAKBox, part # BAK92120. It can be folded down out of the way when you're not using it or turned into just a shelf instead of a box. I've linked a video for you to take a look at. It's with a different tonneau cover but it fits the same wth your MX4.
