Anyone add a Roof Rack? With out using the clips that attach to the door? Does the the 2020 sierra Crew cab have fixed mount points?

.02 You can pop in the roof with slight pressure from your forefinger. I wouldn't chance anything other than what is offered as GM accessories covered under warranty on their website which appear to transfer weight at the ends of the roof over the door frame.
