Well your not looking then. There are hundreds of threads and posts since 2021 on the 5.3 and 6.2 gas motor having defective lifters which can lead to bent pushrods, and wiped out cams. The entire top of the motor has to come off just to do lifters and pushrods. If the cam is wiped the front has to come off. Its a huge job. And a huge problem. There are TSB's out from GM and it appears to be just a matter of time because it it a bad design, but mainly a defective part that causes a BIG job. Its a real shame, because its such a great truck in so many other ways, but at this price point, this issue should not be in your head when going on a family road trip!!
