Retractable Tonneau Cover for 2026 GMC Sierra 3500 Long Bed
Published 09/17/2025
Question:
Hi, I have a 2026 GMC 3500 DRW Long Bed. Im considering the RetraxPRO MX Hard Tonneau Cover RT80485. Can you please confirm that it weather tight, works with DRW, and works with the GMC tailgate please. Also, its not clear to me how one retracts or closes the top does one just pull it open or push it closed? Is there a similar product you like better for my truck? Lastly, can you tell me more about the Rebate offered/included please? Thank you!

Hey Michael, yes the RetraxPRO MX part # RT80485 does fit your 2026 GMC Sierra 3500 long bed dually with the multipro tailgate. It is mostly weathertight but if you were in a heavy rain it would allow some water in which there isn't a way to avoid with tonneau covers. This has a retractable cover that will pull itself into it's spool that is in the front of the truck bed. If you watch the attached review video I attached you can see just how easily it can slide forward and back.
I really like this cover and would recommend it highly.

Thank you! Is there a powered version that fits? I didn't see one for the 8' bed.
