Hey y'all, my name is Tyler and I'm new to the forum and to GMC. In the past I've owned Chevy Silverado 1500's, one of which was a Trail Boss, but I've never owned a GMC or a 2500 until now. I just bought a 2022 Sierra 2500 AT4 with the 6.6 duramax so I joined the forum to learn a little more about aftermarket upgrades and connect with people with similar interests. Anyway, look forward to meeting some of y'all and learning some stuff along the way.
I'll post some pictures of the new truck once I have some time to take good ones
