My 5.3 did this with maybe 800 miles on the clock. I have a vid of it and it sounds identical to yours. It was very loud and sounded terrible when I would accelerate. Took to a dealer, showed a vid, they could not replicate, and I have not heard the noise since. It lasted 15ish miles. I had just put my 3rd tank of gas n the truck and assumed it may have something to do with that. Station in the middle of no where kind of deal.

My Extang Trifecta fits, but with the auto down tailgate, it binds a little. I moved the cover toward the cab so it would go down automatically but now I get a little water in a heavy rain. I'm fine with it for now.
I was looking for some exhaust vids on YouTube and I ran across the below link. I think it sounds incredible! Quite a big price tag, but my worry would be sitting at a light and it stops/starts or the active fuel management stuff. Does anyone have any experience? https://www.corsaperformance.com/collections/2019-gmc-sierra-1500-crew-cab-short-bed-5-3l-v8/products/3-0-dual-rear-exit-cat-back-exhaust-system-21028-sport-sound-level-no-tips?variant=15400519499862
Sometimes I have the lines, sometimes I have one line down the middle and other times I have nothing. Super frustrating. The wider camera angles (even the thinner one as they give you two options) is still almost too fish-eyed compared to my 2015. I was very confident backing in a space. Now I am not as confident with the 2019 one on my AT4. Maybe I will just get use to it.
I have a 5.3 and I think it's fine. I don't need the power to tow anything but my boat. For the extra money, I think that is cheap to get the 6.2 (cheap being that it's factory power) I wanted a truck, so I got the one I liked. If I were buying a muscle car, then yes I would buy the bigger motor... always did
