I was going off the vin number lookup function in the camping world towing guide (https://rv.campingworld.com/towguide) For example, vin # 1GCRWBEH3MZ116570 is a 2021 Silverado 1500 Custom with the 4.3L V6. Enter that vin and it returns a tow limit of 9700. If you enter vin 1GCUYDED1MZ106911 which is a 2021 Silverado LT with the 5.3L V8, it returns 9000 or 9100 depending on bed length. Reason I'm asking is the price difference is HUGE.
