    2020 GMC 2500 AT4

    This truck is the truck that all others should look up to. It rides great, will tow a house, runs smooth, and gets great fuel economy. The Allison transmission is so smooth. The AT4 looks great too.

    Most convenient options on any vehicle I've owned.

    Great power and yet great economy. Love the safety features with the cameras and side vehicle warning. Camera that shows side of vehicle, including trailer when turn signal is on is great. Also appreciate the bed camera for hooking up gooseneck trailer.

    This is your Truck

    When looking at price point vise equipment, This is your truck. I looked at every 2500/3500 on the market, same vehicle equipment and price. I chose the Duramax.. HP, Torque of this Diesel, truck equipment that the SLT price point had everything that I wanted for safety, appearance and comfort, none other came close. This is your truck...

    So far have loved my 2020 2500 HD 4x4 diesel

    I have owned my truck for a month and two weeks. Two weeks after owning it my power steering went out for about 25 miles then was OK again. Last week the check engine light went on and after about 25 miles it turned off and it was OK a week ago I entered my truck to start off for the day and everything was dead absolutely had no sign of life. The dealership has now had it for exactly a week and they cannot figure out what’s going on. They say they’re having problems receiving communicating. I sure hope I will continue to love my truck. It drives like a dream and pulls like an ox.

    Great product from GMC. I used to be a Ford person but this truck has converted me to GMC. Great ride and stability. Nicely appointed interior with lots of room.

    DEF system nightmare

    love the truck but can't drive it now than 2,000 miles without sending it back to the dealership. Had the entire emissions system replaced at 4,000 miles. Then at 5,700 it went into low power mode and was stuck in a regen cycle. The dealership is saying it's "driving habits" but there's no way you shouldn't be able to drive an $80,000 truck less than 2,000 miles before you have to take it back to the dealership and pay a huge fee ($600) for them to force the Emissions system to regenerate. It has to be a computer issue. Steer clear until they eliminate the DEF systems.

    GMC Sierra 2500 HD

    This vehicle has a history of being an excellent work vehicle. People keep these vehicles because they stand the test of time. If there is a used vehicle out there, it probably has a problem which is rare. They are very good work trucks.

    This is one nice good looking truck.

    This truck is eye catching inside and out. This truck is a little intimidating at first because of it's size. With the lane departure it lets you know your well inside your lane.

    Vastly more powerful than our 2015 model

    This truck has every comfort and seems incredibly capable of all we ask. I have only had it for a couple of months but so far when pulling and driving it is a dream. Like most 2500 or 3500s it does not turn on adime but once you have that mastered. it is a breeze. Really like the cooled seats, wish they would learn how to properly cool or heat a cabin. Back seat has room for miles and is the number one reason we chose it.

    beautiful work truck

    this pickup is the ultimate in work vehicles. It will do anything i will need it to do without question. It doesn't smell like diesel which makes my wife VERY happy! I only gave 3 stars for value for money because I believe vehicles are way over priced in general. Walser is very competitive with their prices if not lower.
