Well, maybe I misfired. My boat, outboard, and trailer comes in at just under 4000 lbs so I figured it’ll work if not ideal. I hope my experience is better than some here related.
I Have a 2005 Colorado Z71 4x4 crew cab that I bought new and still have, although I just picked up the 2021 ZR2 that will replace it. The 2005 has been very serviceable, but dull. The jury is still out on the ZR2, but that truck is a beast and a blast to drive.
