Hey everyone,

I’ve been lurking here for several months, thanks for all the free advice!

I was recently given a new work truck from the great company that I work for. It is a 2021 Chevrolet Silverado LT. I have also been in the market to purchase a new travel trailer, so I want to know what rear end I’ve got. I would also like to know if it has the max trailering package, however, I assume it does not.

When I enter the VIN number, 3.42 gears are listed. However, the RPO codes are showing 3.23 gears.

The truck came standard with a factory brake controller and Rancho shocks in the rear. I am hoping obviously for the 3.42 rear end.

Here is what I am looking at on my end. The RPO codes were generated from using a QR code scanner taken from the barcode inside my driver side door. Any ideas? Any help is greatly appreciated.
