Question:

Hi. We have a customer looking to a bed cover T-80482 and also cross bars. I am having trouble finding the correct part number or numbers for a pair of cross bars. Also inquiring about becoming a vendor. Thank you

We definitely have that model! The Retrax T-80482 is the exact same as the RetraxPRO XR Hard Tonneau # RTX78FR. This cover is confirmed to fit 6-1/2 foot beds of the 2021 GMC Sierra 1500. It also comes with the Trax T-slot rails. Sometimes manufacturers use different part numbers to identify the exact same part. This is the case with the # RTX78FR.

As far as crossbars, there are a couple different options.

If the customer wants more of a low-profile look, I recommend using the Rhino-Rack Vortex Crossbar System for Retrax XR Series and Mountain Top EVO-M Covers # RRVA165B-RRRLT600. With this system, the top of the crossbars sit only 4-3/16 inches above the rails. As far as weight capacity, it comes with a 220 pound maximum. It also comes with locks in the legs that lock to the bed.

For a higher system, I recommend using the Yakima OverHaul HD Adjustable Truck Bed Ladder Rack # Y01151-58 with the Tonneau Cover Adapter Kit for Yakima OverHaul HD # Y01155. This rack comes with a 300-pound on-road weight capacity and a 180 pound off-road weight capacity. The uprights on the OverHaul HD have locks that secure the bases to the bed. Also, you receive the benefit of having crossbars that are height-adjustable from 19" - 30" above the bed rails.
