I currently have a 2017 Colorado Z71 with 55k miles I'm looking to upgrade to a bigger truck. I was wondering if there are certain years or builds I should stay away from or that I should seek out. I'm leaning toward the 6.2 liter but the lifter issue is concerning. I hear it was really bad in the 9/1/2020-3/21/2021 builds, is this true? I only plan on towing a camper in the future that will weigh only about 5k - 7klbs. I'm open to any advice.
