Access Tonneau Cover Toolbox Vinyl 6 1/2ft Black For 19-22 Silverado 1500 62389 Fits select: 2019-2023 CHEVROLET SILVERADO, 2019-2023 GMC SIERRA

I bought this because of my toolbox, which is a 19 inch depth. That being said, I made some modifications and while the seal provided was great, was not enough to keep water out of the bed of the truck. The gap or space from the beginning of the truck bed and the placement of the toolbox nearest the back glass was large. Too large for any weatherstripping, so I went to Lowe's and got a L shape metal bracket, painted it black and added that to the area between the truck bed and the toolbox. This worked great, using double sided tape and some sealant to ensure there were no water gaps. The rest of the product was great, definitely would recommend a second person to help, doing it by yourself would be more difficult for sure. Looks good installed, very easy to unroll and roll out. The truck bed must be closed first, and then you can close the cover. Bed will open without opening the cover which is convenient. Overall 5 stars. Tip If your toolbox depth is on the shorter side, doing something similar would be a good option.

Overall really like the tonneau cover. Installation instructions were vague in the toolbox part. But I figured it out. Definitely happy with end results.
