Hello all,
I just purchased a lightly used 2021 AT4 Duramax with 21000 miles and am loving it. We currently have a 2019 Trail boss as well so it is very similar, but has a lot more features. Anyway I have attached as couple piucs and cant wait to learn as much as possible about this power plant and truck.
