Question:
I have a 2020 GMC 3500HD Crew Cab. Regular bed but not a short bed. Its not an 8 but this model year, they extended the regular bed by some inches. Just wondering if these rails are the correct length for my bed?

Expert Reply:
I have another option for you, but the Base Rails for Thule TracRac SR Sliding Truck Bed Ladder Racks # TH21782 you were looking at are designed for 5-3/4' beds and will not fit the 6-3/4' bed found on your 2020 GMC Sierra 3500 Crew Cab.
Instead the correct Base Rails are the # TH33JV which are confirmed to fit the 6-3/4' bed on your Sierra.
