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.🙂

[@CmdrRodgers]

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

[@coryw.9086]

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

[@shucks_sesd_6195]

@@coryw.9086 good power

[@wartowne]

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

[@agentstevehaines9164]

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!!

[@direwolf417]

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

[@kevinhanley2012]

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.

[@joelcrow]

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

[@GenerationOldschoolEspañol]

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

[@dalelangehennig161]

I love these trucks! I have a 6.2 in black SLT. Had a 3.0 before and while I like many things about the 6.2 I love the 3.0 SO MUCH I really really miss it. My wife’s Yukon is a 3.0 and it is such a dream in daily driving. Smooth as butter from the bottom end. I think the stiffer GM seats are better for holding up over time. Such a beautiful truck. Thanks for the great content!

[@Cstanton04]

My 23 6.2 averages nothing closes to this. All about those smiles per miles baby!!! I think I’m around 16.5 if I manage to get the lead outta my foot somedays LOL both are absolutely amazing engines in my opinion.

[@randallmoran187]

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.

[@eunicemilton3512]

I just purchased a 2023 black Denali truck 6.2 engine with 6k miles with cover liner and running boards and me and my baby love it

[@ezm6153]

I have a 22' GMC AT4 with the 3.0 baby duramax - as you mentioned the fuel economy I'm getting is far better than what was posted - I am surprised to see that. Mine has 60,000km (~40,000 miles) and had a few issues with the emissions light coming on - but the dealer replaced some components and the issue resolved itself. There was no effect on driving, just a silly warning light and a day in the shop which was annoying, but under warranty. Myself, I find the seats great and I find everything comfortable .... so I'm sure different people with different body types may or may not like the seats. I do not tow anything over 5,000lbs and I find the truck to have more than enough power and, surprisingly, still pulling my boat up long hills driving over the rockies without any strain on the power train - it's actually quite amazing how well it pulls up and over the Alberta/BC Rockies. So far, so good, far better compared to my F150 with the 5.0 in every way and my pervious 5.3 gmc gasser .... truly the best choice of engine in this truck as far as I'm concerned.

[@timfast8306]

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!!

[@vanlifebiker]

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.

[@charliefreeman2260]

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

[@ES44AC-2]

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.

[@ericmackison9517]

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.

[@Kenopshi-q7c]

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.

[@Kenopshi-q7c]

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 💀💀

[@Vandantcyclone]

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

[@jonr651]

You should really have got the max tow package with this truck. Mine is a 2024 SLT. The higher final drive ratio makes this a dream towing machine! I get 12-15 mpg towing my 6000 lb trailer, which is less than half the capacity. An added bonus of the lower rear end is it addresses the other gripe you have of speed: My experience is this thing is wicked fast, especially in the 30-50 or 50 to 70 passing scenario. The torque is just there at any speed. I had a 2018 Denali with the 6.2. I think this is faster in real world driving. The 3.73 rear end doesn't hurt fuel economy either. My best is driving across a straight flat section of northern Michigan at 55-65, I got 36.8 mpg!!! My daughters Ford Focus doesn't get that! With the bigger rear end, it pulls like a train, combined with the 10 speed, it never feels strained. There is always the right combination of gear, engine speed and boost that make this powertrain combo phenomenal! I had a gas 3/4 ton 6.0L GMC before this, and this blows it away towing the same trailer. Time will tell regarding reliability, but so far, I can't recommend it enough!

[@smmsak15]

@@jonr651 max towing isn't available for the denali

[@RussellFrench-f8r]

I averaged 15 MPG all around driving on my 2023 ZR2 with 6.2L over 40K. I traded for 2024 ZR2 with 3.0L DuraMax LZ0 and at 5K averaging 21 MPG all around at 5K, with a best 30 MPG on a 150 mi road trip, 70-75, flat terrain, slight tailwind. I like the 3.0 better. Diesel also $0.40/gal cheaper in TX vs 91 premium octane as of 9-24.

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

[@danielwalsh7373]

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

[@LoneWolfSparty]

I've heard that their original seat supplier had issues keeping up with demand so they had to bring in another company. Not sure if it's true but it might be.

[@martyanthony4116]

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.

[@newtonbrook]

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.

[@nathanbillingsley42]

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

[@eduardopruneda3557]

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

[@ThunderRunner]

Any issues with the short trips? I work about 6 miles from my house and like to go home for lunch so 6 miles 4x per day would be normal. Considering the 3.0 but worry about the short trips on the diesel.

[@eduardopruneda3557]

@TundraRunner32 so all they have told me is that you need to at least drive on the highway a few times a week. They didn't specify distance or time.

Great video. I am in the market for a new truck. I was concerned about the diesel engine but glad I watched this video. I love your truck. I will try to find one just like it. Your video really helped me. Thank you.

[@shelhawke7206]

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 !

[@billmonroe7328]

If you get the NHT tow package, you get stronger rear springs and shocks as well as 3.73 axles instead of 3.23. Makes towing and hauling much better and helps with soft rear axle. MPG end up being about the same. Seems like nobody knows about it. Just tell dealer you want option "NHT."

[@Kevin-midmichigan]

Do you have the max tow or nht? If so how do you like it and what you towing

[@billmonroe7328]

@Kevin-midmichigan I have NHT. It's great towing and feels stronger around town unloaded due to the deep ratio. I get similar MPG to folks with 3.23 on non NHT with my 3.73. The only downside is that it's a little stiffer unloaded due to stiffer springs, but I don't mind it, and it's nothing like a 2500.

[@billmonroe7328]

@Kevin-midmichigan Most dealers have no idea what NHT is... they think all tow packages are the same. Tell them to look for NHT "RPO". It will show up on the RPO sticker on the truck, and you will get a 13k tow rating on the door sticker if you have it. Test drive and you will feel it's faster off line and a little stiffer unloaded.

[@Kevin-midmichigan]

@billmonroe7328 how much you towing comfortably

[@neilmac4730]

I would love that truck, great fuel mileage

[@AdamFrugoli]

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

[@eddo5617]

I have a similar truck but my with power step side. Anyways I think I’m the unlucky person. At 20,000 miles truck needed a new transmission valve body and yesterday it was on the flat bed to the dealership for engine cooling valve issues. I tow a 21ft boat weight 5,000lbs with ease and you are right on about the gas mileage while towing. I got about 13-14mpg while towing and 30mpg on highway driving. About 21-23mpg city driving.

[@revelationsoundstudio]

Thanks for your helpful review. I plan on getting the Silverado LTZ or High Country with the Duramax 3.0. The Chevy has a sporter grill which I am attracted to. I will carefully check to seat comfort for my 6 foot frame.

[@williamfrost9313]

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.

[@williamfrost9313]

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.

[@PeekabooGram]

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.

[@bradenconway9066]

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.

[@danzante85]

Thank you for posting and sharing such a thorough and thoughtful review. I just purchased a 2024 1500 ZR2 Bison with the Duramax 3.0 LZO. Given the owners manual recommends the use of only top-tier diesel and how scarce access to such diesel is not only in my area in California, but also nationally , I am wondering what other Duramax LZO owners use to fuel their trucks.

[@OUSWKR]

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

[@markreams3192]

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.

[@AmishThursday]

I beg to differ. Ford half ton in the 5th gen 3.5 eco boost beats GM half ton gas

[@lanehart6525]

Current gen F-150's are the best towing half tons ever built. Ecoboost, 5.0, and 3.5 powerboost all tow like a freight train and are very stable. @@TheAverageJoeBro

[@TheAverageJoeBro]

@@lanehart6525 never claimed they weren’t great at towing just not from the manufacturer… I personally feel that GM owns the market stock for everything I stated above which Ford does not do without charging 6K (or more) extra in packages. Cheers!

[@crudedriver]

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.

[@DrKellieOwczarczak]

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.

[@icare7151]

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.

[@slocavky]

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.

If you guys can get 25 mpg then I would get 32mpg as I don't know anyone cheaper and lighter footed on cars than myself. Really, I drive like a roller coaster, always on the sweetspot or less when going downhill, when up I use gravitational as long as possible, and then once it is gone then I go to the sweetspot slowly using gravitation.

[@KingdomChronicles-p9q]

Installing a bigger throttle body and a throttle controller unit in a car can improve performance and driving responsiveness, particularly in cars that are modified or have high-performance goals. Here are the benefits of each: 1. Bigger Throttle Body A throttle body controls the amount of air entering the engine. Upgrading to a larger one can offer the following benefits: Increased Airflow: A bigger throttle body allows more air to enter the engine, which can improve horsepower and torque, especially in cars with other upgrades like high-performance exhausts, cold air intakes, or turbochargers. Better Throttle Response: With more airflow, the engine can react faster when you press the accelerator, resulting in a more immediate response. Enhanced Performance at Higher RPMs: A larger throttle body can prevent airflow restrictions, which is beneficial for engines that operate at high RPMs. Supports Engine Modifications: It complements other engine upgrades, such as camshafts, headers, or ECU tuning, by ensuring the engine isn’t limited by airflow. However, installing a bigger throttle body without supporting modifications (like an ECU remap or intake upgrade) might not deliver noticeable gains and can sometimes reduce low-end power. --- 2. Throttle Controller Unit A throttle controller adjusts how the car’s throttle pedal sends signals to the engine, effectively changing the responsiveness of the throttle. Modern cars often have electronic throttle systems (drive-by-wire), and a controller can manipulate this system for better performance. Benefits include: Improved Throttle Response: A throttle controller reduces the delay between pressing the accelerator pedal and engine response. This can make the car feel quicker, especially in automatic or turbocharged vehicles. Customizable Driving Modes: Most throttle controllers allow you to switch between modes, such as: Sport Mode: Makes throttle more sensitive, ideal for spirited driving. Eco Mode: Reduces throttle sensitivity for better fuel efficiency. Normal Mode: Retains stock settings for daily driving. Easier Adaptation to Driving Preferences: Allows drivers to tailor the car’s behavior to their liking, whether they prefer aggressive acceleration or a more laid-back feel. --- When Combined Synergy of Upgrades: When paired, a bigger throttle body allows more air, while a throttle controller ensures faster and more precise delivery of this air. Together, they can significantly enhance a car's performance and driving experience. Complement Engine Tuning: They are especially effective when combined with an ECU remap, intake, and exhaust upgrades, making the most out of your modifications. Considerations Professional Installation: Both upgrades require proper installation to avoid engine or throttle system issues. ECU Tuning: After upgrading the throttle body, the ECU may need tuning to adapt to the increased airflow and prevent drivability issues like stalling or uneven idling. Vehicle Type: Gains will depend on your car's engine, current modifications, and the intended use (daily driving vs. racing). Would you like advice on how to install these upgrades or additional insights on tuning them for optimal performance?

Your saying the leather seats are not cushy?

[@ScottieRC]

8:50 The seats in GM trucks has always been what’s kept me out of them.

[@chrismarbrey9678]

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

[@CDL62]

What rear end ratio do you have?Thinking my next one will the 3 liter.

[@larrygray1557]

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.

@@larrygray1557 just thought I would mention somewhere in this thread that for Chevys it is called the "Max Trailering Package". Dealer sales folks would tell me it had the "towing package", which is basically just a hitch and elect. harness/connector. I had to specifically say Max Trailering Package to finally find my beautiful new Silverado LTZ.

[@vernonthompson5236]

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

[@Gubers]

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.

Your c plug with a c to c plug will charge fast, or your 110 with a fast charger will do it fast but stay c to c plug

[@grggrs]

For those who have a 3.0 LZO, how is the air conditioning in extreme heat. My concern is the smaller engine having trouble cooling the entire cabin when it gets super hot here in Texas.

[@BTBRVReviews]

It's great....up front. The rear AC vents are small, not very adjustable and don't move much air. The front is fine and cools very will. Pickup truck manufacturers really need to offer SUV tyle vents in the roof above the back seats.

[@caputa0531]

I'm considering this engine however I heard that GM wants only Top Tier fuel. I don't have any stations that sell that fuel near me so I believe you would have to buy the recommended AC Delco fuel additive. Considering the cost of the additive, it seems that it would negate the fantastic fuel economy. Anyone out there have any answers?

[@Kevin-midmichigan]

Do you think the max tow package (13k) would be feasible for a 10k travel trailer in your opinion or would it just be too much for transmission in the long haul...trips roughly 2k round trip. Thanks

[@OH3REDFIRESVT]

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

[@billharris3335]

What rear bed cover do you have on your denali

[@diyjeff1838]

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

[@nlken7175]

I just bought a 2024 trail boss with the 3.0L. Fuel economy and power puts my 2021 Tundra 5.7L to shame.

[@chadclark5204]

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

[@kevinhill9532]

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.

[@garnettsailor1605]

Any crazy oil useage?

[@docmccarty]

What seat cushions did you buy?

[@JoshKilen]

nice video, how would this compare to the Chevy version?

[@BTBRVReviews]

Pretty much the same truck. I personally like the front of the GMC better.

[@mrrvssts]

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

[@Kevin-midmichigan]

Just asked basically the same question...did you get the tow max?

[@mrrvssts]

@@Kevin-midmichigan yes I got one it's an awesome truck so far. I haven't towed with it yet but will soon.

[@lukegkohler]

@@mrrvssts I just got a ‘25 with Max Tow, it’s simply awesome and no giving up on MPG’s either

[@BC_Hunter]

How’s the oil consumption?

[@OpenAirAdventure]

Beautiful truck

[@gavinbrake5672]

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

[@nq2847]

Any oil consumption issues?

[@BeerHunter1953]

Have you noticed excessive DEF consumption when towing?

[@geraldringham8432]

Wonder how mpg would be pulling my bass boat?. 2,100 lbs give or take a few.

[@BTBRVReviews]

Probably extremely well
