We installed a crossbars onto a 2020 GMC Sierra. This crossbar setup was manufactured by Rhino Rack, using their QMFK08 fit kit which sits into the existing weather strip location; we were able to then attach the quick release RLT 600 feet. The crossbars for this setup used VA150B, these crossbars feature channel mount capability and have a weight capacity of 165lbs. This installation was tedious and should be done by specialist.
