I have a 2019 Z71 4x4 RST quad cab. Of course in my short test drive the truck was so smooth no noise. I drove it about 100 miles and the roof started popping. I’m not a happy customer. I paid extra to have the material inside my wheel wells to make it quieter lol! What a joke. 50,000+ on my truck and it sounds like Little Rock’s or acorns are dropping on my roof all day! It even does if not moving! I can be siting in my truck in my drive way but driving it fir hours and it pops. I owned a 2015 GMC Sierra and it was a solid truck. I hope they figure this out! Plus my drive auto window is messing up
