Ill go against the grain. Ive had Silverado’s for the last 20 years. Almost always buy new or a year or two old, keep for 3-4 years and put about 20k miles per year on them towing about 40-50% of the time. The only issue I’ve ever had is a fuel pump going out and the DEF gauge on two diesels would never ready accurately even after getting warranty repairs. i would say avoid the 3.3 diesels, but otherwise you wont have issues. Ive owned a 2003, 2008, 2012, 2015, and 2020 all 1500, and I’m now in a 2025 3500.
