2020 Chevrolet Silverado 3500HD LTZ - Shadow Gray Metallic - 120,425 Miles - 4WD - Duramax 6.6L V8 Turbo Diesel - 10-Speed Automatic
Built like a tank, drives like a dream, and hauls like a legend. This 2020 Silverado 3500HD LTZ isn't here to sip lattes-it's here to tow your boat, your trailer, and probably your in-laws camper too (whether they asked or not).
With a Duramax 6.6L V8 Turbo Diesel under the hood and a 10-speed automatic transmission, this beast is more muscle than most gyms. Got something heavy? It's already laughing. Need to conquer a mountain? It's already packed snacks.
Shadow Gray Metallic paint gives it a classy edge, because even heavy-duty trucks can look sharp. And with 120,425 miles, this Silverado's just getting warmed up-like a diesel-powered fine wine.
4WD means business whether you're on a muddy job site or pretending your driveway is the Baja 1000. LTZ trim brings the comfort, so you don't have to pick between rugged and refined.

Awesome truck
By Imharley | on Tuesday, October 20, 2020
This is the first Duel wheel I have purchased, I went with all options and the 6.6 gas engine, It has great power, and drives smooth, The departure warning is a must, it’s a full 22’ long, so you do have to pay attention when putting in the garage, in a 24’ deep garage you have Two inch’s front and back when parked, I haven’t towed with it, I bought it mostly just to go here and there.… - 3.0
strong yet broken
By Peter D | on Wednesday, December 18, 2024
Thanks to the emmissions systems, GM gets an average rating. This from my understanding isn't only a GM problem, rather its a modern diesel emmissions issue. I do have problems with the sensors built into the coolant overflow tank and def tank, when that part failed, twice, rhe entire tank needs replacing, really a huge waste of money. The sensors should be replaceable easily.… - 5.0
