Hi Bruce!

The Access Toolbox Edition Soft, Roll-Up Tonneau Cover # A63FR will indeed fit your 2021 GMC Serra 1500 SLT with the short bed and your toolbox. This can be used with toolboxes that measure 19" to 21" long, so you are good to go!

Is this for your work truck or are you going to be carrying other stuff?

The use is for my personal truck to keep luggage and other items dry when taking trips.

@BruceL Gotcha. This cover would work very well for that. I have a lot of confidence in the Access covers. They are American made and just get the job done. I've see picture of their testing with 3 or 4 feet of snow on them (they test them in the Dakotas, so you know they are sturdy. I think you will like it! ^___^
