Mine is just over 51,000 miles already. 100% satisfied with it. Gets amazing fuel economy. Zero problems so far.

I've had my '23 SLT with the 3.0 for almost a year now with almost no issues either. Got an Everlasting Comfort seat cushion so solve the seat issue. I'm loving it and plan to keep it until the wheels fall off or I leave this world, whichever comes first.🙂

Amazing fuel economy results! Wish I got similar magic on the 6.6L 2500HD. Its like half that mileage empty without tow 😢

Got a 23 LTZ with the LZ0 and absolutely love it and rave about it to people. Have only owned it 3 months but man its a SWEET truck!!

I just bought a new 2024 Black Denali. Thanks you for your review, it made me feel comfortable with my purchase.

Awesome review. Thank you for what you do!

Same exact experience of my 2022 GMC Denali. I love the truck…

Man the interior is so nice. Like a nice high end cabin you feel secure in from all weather and harms way. True Dreamliner.

Strange to think y’all have had it for a year! Time flies sometimes!

Very good observations on your truck. The lack of 12v was a bone headed idea. I really love my 22' LT Trail Boss 6.2L . The Diesel is a fantastic option, I just wanted another 6.2L.

I bought a new 2021 Silerado with the 3.0. So 3 years, no issues. Average 24 mpg. Only seems to use DEF when towing. When towing 5k trailer, I average 12 mpg. But has plenty of power to spare

That towing MPG is insane!! I tow a 26' TT that weighs about 6500#. My tow vehicle is a RAM 3500 srw with a HO CTD and the best I get is 10-11 around 70 mph.

I have 5500 miles on my 2023 High Country 3.0 LZ0 and really like it. I traded in my 2020 2500 6.6 Duramax and really liked that also but the ride was rough. I miss the power of the 6.6 but the 3.0 is no slouch. I agree with your likes and dislikes but an addition for me would be the camper mirrors that don't offer auto dimming Great video on a nice looking GMC!!

Thoughtful and objective information. I drive a 3.0 Silverado and have experienced the same level of satisfaction.

I can’t decide between the Chevy and GMC

Have a 2020 SLT, really like the truck, almost 75k miles. Has had a coolant pump leak and oil leak fixed under warranty. Brakes rotors warp too easy, may be the stop and go traffic. I average 27.5 mpg with highway and heavy traffic on the commute home. Seats suck, I added a purple seat cushion and no more issues. I also added the roadmaster suspension. Helped with towing my airstream. We'll see about the next 75k miles if I would buy another one.

I just got the 2024 GMC sierra 1500 with the 5.3 v8. I’m happy with it.

Good call on keeping it! It’s a beautiful truck, reliable and has excellent fuel economy. Thanks for the 1yr update 👍

Wow, i was just reading this comment and yup, it happened. Haha

I have the 2022 refresh with 20,000 miles on it. ..essentially the same truck. I love the truck. It is a incredibly smooth and comfortable truck. The only difference is I have the 5.3 (with no AFM due to chip shortage) . I would agree with this review. The only slight difference is the review of the seats. The seats are definitely firm. However as a tall person with back issues, the seats are God sent. My 5.3 fuel economy in my opinion is excellent for a V8 gas engine. Up in Canada the fuel cost for diesel is about 15% higher. I think your fuel economy in the long run would warrant the extra cost of the diesel engine. Not sure of the increase cost of engine maintenance though. I would love for you to do a video on options for a beefed up rear suspension options, taking into account the adaptive ride suspension. . Springs ,air bags or Timbrens?. I do not know. Thank you.

I would love that truck, great fuel mileage

"Dang". The official non-word of this channel

I have a 22 trail boss LM2 refresh. 20,000 miles. No complaints. I don’t even mind the seats… Had a couple trips with a 20’ enclosed trailer and a 3500-4000lb car. Averaged anywhere from 15-17mpg.

2023 Denali here with 20k miles. Absolutely love the truck and engine/ transmission combo. Fantastic duo. The 3.0 Duramax and 10 speed has to be one of the best on the market. Hands down. Miss a sunglasses holder as well as a 12v outlet. Such a strange omission. Google is awesome. I love that you can kill the door honk setting (as opposed to my Ram). Also love that you can completely shut off all exterior lights. I don’t love the back seat lift catch mechanism. It’s sticks. Seats are ok but not great cushioning. The leg position is excellent and it’s easy to sleep in the passenger seat while traveling. The wind noise is annoying. Ram beats the heck out of GM for a quiet interior. Agree with this review entirely

If you get a chevy custom trail boss with the 3.0 duramax, it has the smaller radio and comes with a 12v socket

Nice to see an update from you. And doesn't seem its been a year yet. I got mine not long before you did. I have a 21 with the LM2 and I went from 10k miles on it (got it used) and now I am at 31k. Zero issues and I still love it. Have you thought about the RAS road master active suspension for the soft rear suspension? I plan on it this year.

just get airbags

Your video is the best I have seen on the 3.0 Duramax. I have a 2021 Denali and it is the most impressive truck I have ever owned (79 years old and have owned about 10 trucks , all GMCs). Currently it has about 63000 miles on it and it averages 30-35 mpg on the highway and always 25-30 mpg around town. I'm light-footed and a very conservative driver. Due to my own distraction I recently put some DEF in the wrong fill port and was surprised to learn how many others have made the same error. Please convince GMC to put the DEF fill back under the hood or on the other side of the vehicle. I know, I should get a cap or T-shirt with the word "STUPID" on it.

I have a 20 SLT and have complained about seats since new. Been going to try the memory foam or something but never did. Will try now. Did talk with upholstery shop and was told it would be worse if installed under leather.

I love the creativity in your videos.

Great review … I have the same truck but with the 5.3l gas engine . I echo your comments about lack of 12 V chargers! My wife’s stand up board needs a 12 V charger to inflate .. as well as my portable air compressor .

Sounds good

Beautiful truck

I've been averaging 30 MPG & my record in 50 mile setting is 44 MPG. These trucks are insanely efficient, love my 2023 Elevation LZ0.

Gm did something with the seats for 2024, I have an in-law that has 2023 Silverado and the seats in that truck are about as comfortable as a metal folding chair. They are so uncomfortable I counted gm out when upgrading my truck last month, however my local ford dealer decided to play games with me so I went and looked at a 2024 2500 Denali and there is a very noticeable difference in the seats, much more comfortable! Granted they’re still not as soft as what I had in my last ram but the seats are plenty comfortable for me

Diesel vehicles get better fuel economy period. I don’t know what the current figures are but at one point 51% of new vehicles sold in Europe were diesel because of the high price of fuel. Until this point GM is the only company to do half ton diesel well. Any half ton truck towing a travel trailer should have rear suspension enhancement. Sumo springs or air bags would make towing with that truck much more comfortable. I use Timbren springs on my Tacoma which makes towing much more stable. That’s a very nice truck.

@TheAverageJoeBro

GM has the best towing game in the market for the half ton class. Every truck and every trim come ready to tow, no need to replace the hitch… ahem Ford. The suspension and frame are unrivaled, independent suspension on say a Tundra makes for a better ride but can be challenging when towing. Which is why GM still employs the leaf suspension. GM also adds on-board TSC as an option on most of their trims. My truck came with TSC no extra charge. I’ve towed 7500k with mine… felt like nothing.

It’s hard to believe it’s been a year since you got it. I guess time flies when you hit 50 🤣

I tow all the time and I have not used a 12v plug since I had an old flip phone. If I need beacon lights I have bought battery operated LED beacons and they last for a very very long time on 2 D batteries, I actually have yet to have one run out of batteries and I’ve done at least 1500 miles of wide load hauling or being a pilot vehicle.

The lack of 12v outlets is silly on GM's part, considering no more than they would've cost to include. I would think that most people would prefer to have them and not need them, rather than need them and not have them.

Great Review! Have you tried the sierra/silverado with max towing package? I am thinking of getting one. Thanks!

Beautiful trick

Very good looking gmc I own few and would not trade them for anything

Thanks for the review. What would you estimate the fuel economy to be towing 3-4K with a trailer not as tall as rv? What rear axle ratio? Thanks

Great review. Where you do pay is at the pump. In some states diesel is alot more expensive than gas.

Awesome review! I’m looking at getting into a newer gmc pickup , 2021 or 2022. Are those 3.0 the same as the new trucks? I’ve always had 5.3 . I can’t believe the fuel mileage on those 3.0

for got it a 3.0 its amazingly quite for a diesel.

First off, I'm a ford guy, but because I see such incredible fuel economy with these engines, it looks like I will be switching brands when its time to trade out of my 22 tremor, which has been nothing but trouble since I got it !

I would love to see some head to head comparisons with the F150 powerboost

GM needs to: 1. Use multi density foam in their seats. 2. Have rear self leveling air suspension. Firestone does offer an additional rear air suspension.

I wish that they would offer this engine in a long-box regular cab. I do not need the rear seat for my use case, but oh well. My concern is that, as a 1500, it will be too squishy. The "firm" seats sound good to me, so I guess I might go check it out.

I bought mine 9 months ago and have put 48k miles on it. Over 90% of that is with a 6k lbs trailer behind it. After installing a Roadmaster HD spring, I have no complaints when towing. The interior is not my favorite; the seats are too stiff. You can feel the pain in your rear end after driving for over 3 hours. No drivetrain failures or any maneuver problems. The forward assist warning was defective several times in clear weather; disconnecting the battery fixed that. Parking brakes kept failing to engage in the first 10k miles. I went to the dealer three times to switch out parts, and it runs well now.

Road feeling is nice, actually feels better than my ram with air suspension. The diesel has enough power most of the time. The biggest disappointment is the automatic parking brake feature. There's no way to disable it, and all my trailers are parked on a slope. It’s horrible to keep accelerating when lining up the trailer 💀💀

I question your mileage numbers from the direct competition. I drive for a large automotive group and brought back a Ram 1500 diesel from Green Bay WI to Toledo Ohio and it averaged 31 miles/gallon for the trip. Slightly lower than your 34 MPG but close. Nice looking truck.

Just bought one two weeks ago for road trips.

I bought a ‘24 AT-4 in November with LZO 3 liter, it has a heavy duty 110 volt outlet in the bed that runs work tools and a 110 volt outlet in the interior console. GM must have listened! I’ve had 3 Dodge eco-diesels, they all did pretty good on mileage, my ‘14 was the best. It would do 32 mpg or better at hwy speeds. My 15 had suspension issues and my ‘18 lost the motor under warranty luckily. Overall put around 250k on them total and loved driving them. However my new AT-4 blows them away! I must admit the Dodges seats were more comfy though.

Update we just drove from Boise Idaho to Cheyanne Wyoming today. The AT4 3 liter at 75 miles per hour the whole way, averaged over 28mpg. That’s a lot of up and down hill travel. We had 2 people plus 600 plus pounds of gear. We used to have a Dodge Eco-diesel but the motor went out, luckily under warranty. It was very close mileage wise but the GMC rides much nicer and has better features. Love the steering assist. I also bought an everlasting comfort seat, it makes all the difference.

Miss the seat in my 2016 Chevy. I have a 2022 GMC 3500 and would like to know what cushion you found that you like.

I have the same exact truck and the only thing that disappointed me was how much DEF it uses when I tow .

I pull our camper have the longer wheelbase with the 6'-7" bed. I've towed with the shorter one as well, and there is definitely a difference. I wouldn't want to pull ours with the shorter one. 32' shadow cruiser.

Currently own a 2016 Denali 5.3 and now looking at a 24 with the diesel. What is your final drive gear ratio?

I have nearly 23,000mi on my 3.0 and it's a beast! Lifetime 26.3 mpg last 5 months I've used it 6 days a week in a lot of short trips going up and down an 8 mile stretch, about 400 miles a week getting about 24mpg and 30+ on the highway

I have a 2023 Chevy 1500 LTZ with the 3L. I love the truck. The MPG on HWY is WONDERFUL!

agree, yep seats and lack of 12v plugins and only problem with the google assistant, to get the full benefits, after the free trial expires, you need to subscribe to bare minimum On-star $15.00/month plan 😐

Wireless charger is in the perfect location and seems to charge the phone fine. Easy to forget phone is in there and leave it behind when exiting vehicle

Can you do a video on the foam for the seat you did. I agree the seat are awful.

Also looking right now with the 3.0L Duramax #1 consideration. Not only the amazing fuel economy but would also be a daily driver which pushes me away from the 2500...as the backup is the wifes Fiat 500. Thanks, but no thanks! Wish Denali offered the Max Tow Package as but available in lesser trims including the SLT I could live with. Switching to Chevy it is available in the High Country trim. That $800 option solved a lot of your issues with heavier rear springs, trailer tuned suspension, rear axel increased to 4100 lb from 3800, more of a towing 3.73 rear axel, but more important, the higher GVWR supports higher combined weight rating 15000 to 19000, conventional to raises the 8000 to 12900, tongue weight 800 to 1290 with load at 1675. Even with a RV similar to the Surveyor, that is almost a nobrainer for towing.

The MPG is insane.

I agree with you on the 12v, should have a minimum of 2. I also hate Gm seats, my titans are better my dad's 2018 Chevy hi country suck. Dislike driving it.

Anyone know if the Denali Ultimate seats are more comfortable?

I wish duramax would make a big boy 6 cylinder based off this engine.

100% agree on the 12v and USB. Like, seriously. How does any modern truck let alone a top of the line trim on a luxurious truck like this have such low power USB ports and no 12V ports? Everyone has 12V accessories already and phones these days need way more power to charge at any reasonable rate. It's the same deal for their wireless charger. It charges at the same speed as the USB ports. And just craps an error half the time anyways. The only thing I disagree with you on is having a wireless charger and Google services. A wireless charger that holds a phone well is a very nice thing to have in a vehicle, especially one with wireless Apple Carplay and Android Auto. The vast majority of people are going to use one of those because it is personalized (their own phone) and works amazingly well. It's vastly superior than any built-in system IMO. Heck, anyone with a Android phone already has all the same Google services via Android Auto, so what is the point? You have to pay a monthly fee even to use the Google services in the truck which is another obscenely stupid thing about it. I have heard that you may be able to tether a phone internet connection to the truck and use the built-in Google maps with GPS navigation without the ripoff OnStar subscription, but I'm not sure. But again, why not then just use Android Auto or Apple Carplay? It always irks me how these companies cut corners just enough that it won't sway people away. I get it, especially in lower trims. They are a company, not a charity. Their goal is to make a profit and that is it. But on higher trims, there is no excuse. It is only because people still buy these trims. I'm sorry, but what exactly about this Denali is worth $15k-$20k more than my Elevation with premium package? The seats? The suspension? I have the 360 camera system, the Bose premium sound system, the bedliner, running boards, rear power window, adaptive cruise control, power moon roof, leather heated seats, heating steering wheel, 3.0L Duramax engine... And yet you get the same trash USB ports, wireless charger and lack of 12V. On a top of the line trim, everything should be top of the line IMO. Why spend so much more money just to still have much the same complaints about the truck? It's not hard to put in aftermarket seats or suspension if you must. But it's not like the lower trims have really bad seats or suspension. Both are just fine.

Please send me a link to your steering wheel cover. Love the channel.

You are wrong about diesel vehicles getting better fuel economy!! I purchased a 2022 Denali Ultimate 1500 with the diesel. Am pulling a 27 foot Airstream. Comparing to my 2018 Hi Country with the 6.2 gas the diesel defiantly gets much better gas mileage However the diesel gets about 15-20 percent worse mileage pulling the trailer!! Also we travel a number of high mountain passes - Salmo Creston, Anarchist,Roger’s etc. and the truck will not keep up to the posted speed limit- 100 kms. per hour - in a number of stretches- was not a problem with the 6.2. Love the Ultimate but a 2024 6.2 will be waiting for us in 2 weeks time.
