New long-term review vehicle: 2023 Chevy Silverado 1500 High Country 3.0L Duramax Diesel


A new year means a new truck for the outlet, and this year it’s a 2023 Chevy Silverado 1500 High Country 3.0-liter Duramax Diesel. Yeah, that’s a mouthful.

A Chevy Silverado 1500 has been on my list for a few years due to its popularity and my interest in learning even more about the truck. I also wanted to have this experience after spending a year with the 2021 Ford F-150 Powerboost and the 2022 Toyota Tundra. Once Chevrolet came out with a new interior and a refreshed 3.0-liter Duramax Diesel engine, I knew it was time to pull the trigger on buying one.

So, let’s dig into the details. This truck is a crew cab, 4WD version with a standard 5-foot, 10-inch bed. It has the Dark Ash Metallic exterior color and Jet Black interior with Umber Brown accents along with some wood paneling on the doors and the upper glove box.

Typically, I don’t go with the highest trim level, but in the case, I decided to go for it since I wanted as many features as possible to talk about throughout the year. Plus, as we previously reported, the High Country trim is the only one with the 2-speed transfer case AND the max towing package together. Other trims offer a single-speed transfer case (no 4LO) or an off-road package that can’t be paired with the max towing package.

Frankly, I’m glad I got the 2-speed transfer case due to a pretty gnarly drive home from Fort Wayne, Ind., which saw me get stuck in a snow drift — and I had to use 4LO to muscle the truck out of it.

Also, I knew I wanted the new 3.0-liter Duramax Diesel. This is the LZ0 version for those who are aware of the naming convention General Motors uses and has more horsepower and torque than the prior LM2 model. Also, John Barta, Chevrolet assistant engineer for Diesel engines,  told me they made some improvements to the engine which should help with long-term reliability and they fixed the long crank, slow start issue.

Another reason I wanted this engine is because of its excellent fuel economy and towing prowess for lighter loads like a camper as opposed to the fuel thirsty and expensive heavy-duty trucks. The rear axle ratio is 3.73, the payload is 1,461 pounds and max towing is 13,000 pounds.

There is also a fair amount of confusion from consumers on this engine, and I’m thinking after a year’s worth of videos, maybe we all will have a greater understanding on this truck.

What did I pay?

This is also a hot topic for people whenever you buy a new vehicle these days. Trucks have gotten expensive, and people’s initials thoughts were $90k when I showed the truck in person.

This truck’s MSRP was $67,965. Since my dad is a former GM employee, I was able to take advantage of employee pricing, which saved about $5k. Options included the 3.0-liter Duramax at $995, $700 for the Max Trailering Package. I received $125 in credits for GM not installing a steering wheel column lock or the wireless charging, and I got $750 in rebates.

This works out to an out-the-door price of $66,984 at Kelley Chevrolet in Fort Wayne, Ind.

The bottom line

While I don’t anticipate this truck will make the same splash as the 2022 Toyota Tundra or draw the same interest as the 2021 Ford F-150 PowerBoost did, so far it is a solid truck and I’m looking forward to driving it a lot this year.

    Please address these discussions in a future videos or posts:

    1) Does the Max Trailer package increase payload? I think so because GVRW is higher. Please confirm.

    2) I love my the OEM Tow mirrors in my 15 F150 Platinum. They have auto extend/fold as well as heat, BLISS and cameras for the 360 camera system. Please comment on the functionality of the Chevy OEM tow mirrors, especially compared to the Ford. I never thought I could love tow mirrors so much until I got my F150.

    3) Please discuss how the Duramax Diesel 3.0 does in cold weather, especially at start up.

    Potential new story for you to look at. It seems Chevy is not allowing any silverado 1500 3.0 lz0 trim to include the max trailering package (build and price kicks out the 3.0).

    I’d be curious as to why and if/when it comes back.

      Any answer yet on why max trailering package no longer available?

      1. Tim Esterdahl March 8, 2023

        Just got an answer yesterday. Parts issue.
