Question:
I’m having trouble finding this bed cover for an 8’ bed. Do you sell one that will work with a typical low profile toolbox?

Hi Cody; are you looking for a particular tonneau cover style? If you want a soft roll-up cover you can use the Access Toolbox Edition # A62339. We also have the Extang Trifecta 2.0 Soft # EX93455 or Extang Solid Fold 2.0 Hard # EX84455 which are both folding tonneau covers. All of these are toolbox compatible and fit your 2019 Sierra 3500 with an 8' bed.

I have the access toolbox cover on a 2015 GMC . The cover / rail assembly rises up approximately an 1 1/2 from the bed rail , you can see in photos on reviews. Standard tool box & release buttons are on the ends . If your latches are not on the ends & low profile box it might interfere. Would have to take some measurements. Has been a great cover by the way

Thanks Robin. I think one of these will work. I think the issue I will run into is I have to have a low profile toolbox due to my fifth wheel camper and it seems the handle/lock mechanism on most toolboxes will end up right at or below the tonneau cover weather seal. I Would like access to the toolbox when the cover is stretched out. But I could be seeing it incorrectly.
