Fits perfectly and easy to install.

I've installed this cover on my 2020 Silverado when I purchased the truck. Purchased the cover directly from the manufacturer. Two years in and the cover is starting to fall apart. The cloth strip on the right underside of the cover has completely separated from the aluminum roll-up rails and the vinyl material is separating from the cover on the underside above the tailgate (where the tailgate seal is). I've used some 3M spray adhesive to repair the above but for a cover that costs close to $1000 this stuff should not be happening after only two years. I've had regular roll top covers from Truxedo that lasted 10 years plus with no issues ... not to sure this one will last half that.
