I searched for “ where to put my buttons “, and it brought me to this video. 👍

I have a 22 at4X here in Northern Sask. Thanks for the mention of those noisy tires. I have been hoping for a year that hum was just those tires. It's low but constant at 50K/hr. Great truck. I've owned a few. Love the console shift.

[AS-chty]

The white grill and emblem looks awesome!!!

[swill]

Just bought a 2019 fully loaded. Thank you for teaching me about the features my truck has from factory and great ideas to add. Weirdest thing about my truck is a full on metal safe with combo lock in center console

[RVOLUTION]

I purchased a 2022 6.2 before the refresh with the standard box it was used and my goodness what an upgrade from my 2009 SLT 5.3. Ahhhh and I did change the Antenna but not to the bullet one. Great vehicle

[bigdog]

Great review ! I wanted a 2022 specifically because of the interior change and was bummed to hear the release will be delayed. I heard GM has thousands of these trucks waiting for the chips. There could be some deals to be had hopefully in the future when the chips come in as they will have to move the back log of trucks. Time will tell

[johnwinter]

Excellent review. Just bought a Certified 2022 Silverado LTD LTZ (pre-refresh). Picked a 5.3 not the 6.2 or diesel that were right there on the lot as well. Recently sold my 2016 Escalade, so I get the 6.2, and also get the premium fuel. Diesel was tempting, but I have had six LS motors (three 5.3s and three 6.2s) and have been satisfied with all of them. Love the truck and your comments, many of which apply to the Silverado, are right on. Thanks.

[jasonmalone]

Great vid. Loved how you said your likes and dislikes were your opinion.

[CRU]

Nobody gonna mention the Medal Gear Solid video game sound effect when he walked behind the truck?!! Haha! Classic. Nice truck.

[ryanmancuso]

If you tow a lot and/or drive a ton of miles, get the 3.0 L duramax and a banks pedal monster... completely transforms this truck! I’m so happy with mine. I do mostly highway driving and on a warm day, just me in the truck, I’m getting 31 mpg!

[timfowler]

Great video. Your truck look’s fantastic. My last Chevrolet truck was a 1969 with a 250 inline 6. So I have been eye balling the new GMC line. Thanks for your review.

[AshesOfheWake]

Please don't forget this truck has a column shifter as opposed to a knob or buttons. The bed lining is great quality, too. Also, I might be on an island by myself with this, but I found the seats to be really comfortable.

[dubltap]

I bought a 2020 Trail Boss LT with the 6.2, zero issues so far and with zero chrome except the exhaust tips, badging and lugnuts. Which I quickly changed to black.😁

[jasdprintboss]

I was only looking at the Sierra 1500 Elevation a week ago. I saw this video and now I am about to pick up my AT4 in white with tech package this Saturday. And these vehicles are now in very low stock right now and need to get mine 200kms away from Winnipeg. I must admit I would copy some of your customizations. Indeed those are nice! Thank you for the informative video keep it up neighbor from Winnipeg in the province of Friendly Manitoba!

[gmanesquivel]

just got this AT4 this week just blacked out and its a pretty dope truck im starting to like it more than my BMW 440i now

[dejayyjones]

Looking at grabbing one the end of this year. Now that i notice the Denali does have to much chrome.

[kinterest]

Nice! I am getting mine too. 2024 6.2L.

[russbortnem]

Great video. Thanks. I love my '21 AT4. I don't tow anything so went for the 5.3. Ended up getting the rocker arms replaced on both sides. Warranty, but still a hassle. I'm having trouble finding the illuminated GMC front emblem. Thanks again

[cam]

That’s exactly why I didnt want a Denali and went with the AT4 😂. Btw, center console gun safe is the way to go ;)
