best reviews on CZcams good job guys
He and Craig where my favorite from Autoguide. I’m glad to see he has his own channel. Love it!!
Just picked up one of these Steve. Had to get my dealer in Trail BC to ship it from Alberta since there was nothing in BC with the specs that we wanted. So far it's a beast and solid people hauler for the wife and 3 kids.
Late to this vid as I shop for one of these beauties. Definitely a pro level video. Thanks much.
I think they really nailed the new SUVs and I can't wait for the diesels to come out. One minor disappointment is the payload. I think they should've increased the gvwr more payload and towing. I also think they need a HD version that can to 12k or more.
an HD version would probably be made in a different plant, since that is an entirely different truck. But it would be nice.
love that northern scenery ,ill be in your neighborhood for Thanksgiving weekend can't wait
Great job and review on this 2021 GMC Yukon AT4 Truck King Team. This GM line of full size SUV is incredible ... so as the price but everything is so expensive nowadays.
Thanks for working the TT into the testing regimen. I really think it gives a better perception of capability of tow vehicles than a flatbed. Good on you guys!
We heard that said multiple times - so we did it.
Dang man"!!! Your on top of your game and know your vehicles, "!! I seen you doing reviews on other shows even before tfl, you have an exciting personality! Especially when your offroading ir in the mud pit. Great job Steven!
Well said ... TFL truck guys have their favorite trucks and they tent not to give a full fair review ... and talk up the truck they like more and talk less or bash the truck or trucks they don’t like
I just drove my 2020 Sierra AT4 6.2L home from the dealer. Loving it
If I thought I could have gotten a 6.2L AT4 Yukon XL with air bag suspension, I would have waited.
I remember when GM started the first heads up display in the 80s then Cadillac later on and most people said it was silly. Now all the luxury models are adding. Love this Yukon but I’m getting the Tahoe soon.
Great job Steven! I really enjoy your channel!
I appreciate that!
Best big trucks on market. Not even close. Really good way of explaining how one gets used to air suspension by old man and analogy to big trucks.
Thanks - turns out all those years in big rigs was good for something after all.
Once again, great content guys! 👍
Appreciate that
I love your videos and enthusiasm.. :-) Thank You.
Love it! Great video! Thank you
Good review and I always appreciate when you show US numbers also.
We know who's watching.
Top notch review!!
Of note, in the other camera screen there is a split view where the mirror cameras look back down the truck/trailer. That does not time out, you can drive with it like that.
Having had the 2020 GMC 3500HD AT4 for almost 5 months now, I do have at least one "wish", airbags for the rear...
When I hookup my 20+5 gooseneck I'm towing 7200lbs right off the bat, then I load my other truck, 2002 GMC 2500HD, an additional 7000lbs and that puts me at 14200 and that squats the truck by about 2", so my wish would be for the automatic A/B system portrayed in this video...
Mirrors/cameras...One of things I love about my truck, side view mirrors, extendable for towing, BUT there is a twist, when I'm turning corners while towing, I flick the directional on AND the camera on that side mirror shows me a view straight down the side of my entire rig on the 8" infotainment screen...really handy to see where your rig is in relationship to the corner...
I was really surprised at the cost(US), considering that's about(+/-) where my 2020 GMC 3500HD AT4 came in($79,300)...
WI Patriot can you tell me what the payload/5th wheel hitch pin rating for your truck is please. Is it a long box? Thanks
great you did a video with a travel trailer. I have a travel trailer and this video helps me learn. It would be nice GMC or Chevy made rear view mirrors that extend out for when it comes to towing.
I like how you use your dad for comments. I liked how your dad made a great comment on the 5.3 v8. I have a 2014 GMC Sierra with the 5.3 and great engine.
Dad says - thanks
Nice you spot a Bronco on a farm and also what a beautiful scenery where you test your trucks.
Ontario in the fall is spectacular - a little bonus before the winter freezes us!
Enjoy Sr. & Jr.’s comments, very informative. Nice fall colors as well on the drive 👍👍
Glad you enjoyed it
Great review!!!
Great video and I feel well informed about towing with this vehicle.
Great to hear!
This yukon looks sharp, and a diesel.. very nice GM
Thanks for the nice reviews. By the way, you compare the Canadian Yukon AT4 XL with the short wheelbase US AT4 model. So the Canadian should little bit less expensive(around $2000 cad). So except for that, a really great job.
Great review guys. One thing driving in the real world especially in the western US with lots of mountain passes, the 5.3 feels underpowered. I have a 2018 and light trailer at 4k. Loaded up and with passengers this gets maxed out fast. And does feel underpowered at times. Maybe the 10 speed helps?! And they DO have issues with the AFM - Cylinder deactivation is horrible on the vavle train. So the 5.3 is not bulletproof by any means. Local dealer had 3 in for service on the valves with low miles.
Great video. The tow rating maybe legal for this AT4 to pull the Bullit travel trailer. The tongue weight however is probably too high for this vehicle means in real life even when your trailer is absolutely empty and you just have gas and a little bit of gear in your AT4 you are already over the small payload this vehicle has. The little payload is unfortunate since you can't even drive legally with 4 adults and luggage not even speaking of pulling a trailer!
Does the Yukon have the trailer tow side mirror camera view like the Sierra? When I have a trailer connected to my Sierra I can go the camera button and click the mirror option, and I have pretty decent side mirrors in the display that stays on until I turn it off
Awesome review, great to see the new IRS towing something substantial. The Tahoe doesn't use a G80 anymore. It uses a mechanical LSD with clutch packs.
Nice review
Payload payload payload. I’m confounded by why 2500 SUVs STILL have not come back to the market. We need an SUV capable of hauling 6 people comfortably, cargo, and a 30+ foot 7500 pound camper. Someone for the love of god bring back a 3/4 ton XL SUV with a payload of at least 2500+ pounds of payload!
That’s my thoughts exactly. Come up with any solutions?
@@pewpewtactical5288 No unfortunately. Next truck may have to be an actual pickup 2500HD at this point.
@@josiahberry8743 What a bummer. I’ve got 4 kids and in the very near future need a rig capable of exactly that.
@@pewpewtactical5288get a used exurcsion
the only problem with HUD is $800 windshield replacements and in Alberta, we use gravel to control the ice/snow in the winter. you WILL break a windshield every year.
Good and corear review brother nice 🔥💯
Thanks for the review. I own the 2021 AT4 WITHOUT the airbag suspension and also didn’t come with the manual brake adjuster. I actually own that exact Trailer too. Can I tow that trailer without a separate brake controller installation? I was told to purchase a trailer brake kit by the RV company. I do have the TOW option but wondering if I need extra brake item I was told to purchase. Thanks for any help
Stephen, This is another exemplary and very educational video #EqualizingHitch
Good looking rig. Can you get that suspension on a SLT model?
This is the only air suspension system I know of that matches damping with spring rate??
Thank you for actually showing the Trailer specs this time. You really need weight distribution though.
We know. If we owned it, we'd do it.
In other videos showing the 2021 Tahoe Z71 it does not have a g80 rear locker .
i love that moon roof
interesting flt had a 2021 tahoe z 71 and they tried to see if it had a locker and it did not they were spinning the tires no lock up
is the auto locker a special request to the tahoe z71
I’ll take the Tahoe. G80 and traditional suspension setup will always be best especially in the long run
I want one now thanks.
Another👍 for Steve 🇨🇦.
Many thanks for the excellent review and for the great efforts.
Is it true that the seats of the Yukon AT4 are less comfortable than Yukon SLT or SLE?
At4 is just a carbon fiber look that's it
How wide is that trailer? 8’6” or 8’? If 8’6” do you think the mirrors would work with a 8’ travel trailer?
What was your MPG while towing? Thanks
So pumped you left TFL!
Thanks for following along. It's been great coming back home and working with my dad full-time.
Like the information guys! I wonder what you opinion on how the AT would pull that travel trail up grade as in the mountains?
Having towed in the mountains I'd be willing to say it would be OK - not fast - but OK.
3:42 I thought the Chevy also had an E LSD, and if not, it didn’t have a locking differential at all
Hi! And what is the MPG with and without RV?
Does all AT4s come with this adjustable suspension?
There is definitely not a G80 in the z71. I believe it uses the same system, although in TFL's last video with the AT4 they made it sound like the rear end had a different system. They didn't say what that was though...
Great info...nice to see a travel trailer used. One thing...what about wheelbase vs trailer length with all that side area?
Wheelbase is definitely important. General rule I've used is the first 110 inches of wheelbase allows for a 20-foot trailer. For each additional four inches of wheelbase length, you get one foot more in trailer length.
The 2021 Yukon has a 134.1-inch wheelbase (about 4 inches longer than in the previous generation, making it a better towing rig overall), which puts us at 26 feet using the formula. Our travel trailer in the video was a little over 30-feet, so we pushed past the formula, but the setup still felt safe. Trailer/vehicle weight plays a big role as well, along with the suspension calibration, and the Yukon handled this load admirably.
@@TruckKing Thanks for the in-depth exploration, it gets overlooked! Please correct me if I am wrong, the standard Yukon tested has 120.9" wheelbase, need the Xl for 134.1". Only a 20' trailer seems unrealistic for such a capable truck.
This makes more power and torque than my old ls1 gto.
That tablet style infotainment screen is the best I've seen as tablet style goes but having the denali not have it does still make the denali a bit more desirable. Still think if I were getting rid of the stalk that I'd rather have the turn dial. But I haven't messed with those button although has gotten ok review
Yeah I don't mind it. You get used to it quite quick actually. Really all you use is park, reverse and drive (push, pull, pull)
Did I hear you correctly, you can get the 6.2 on the AT4?
Doesn’t the new Suburban and Tahoe come with a mechanical LSD?
I love this
Just want to ask you a question about the toe weight? Is there any way to upgrade the Towing Four 2023 gmc yukon at 4 xl 6.2 v8
only if you modify it - and we have no suggestions about that
Any chance you can also do interior space tests ? Trucks and SUVs. Maybe measure doors , interior floor to roof etc
Ah, go to a dealer and let the salesman work for a living - take a tape measure.
I am trying to sort out which is more valuable the rear suspension of the AT4, or a duramax diesel. For now the denali that i think can have both is out of my price range. The better ride/more stable (therefore safer) ride have strong advantages. The better fuel mileage and lower maintenance cost of the diesel have measurable value. Any thoughts?
You tow sometimes. The diesel works every time you drive. Go diesel.
Also as a note: the Ecotec 3 engines have only been around since the 2014 model year, (The multi displacement variant only since 2019) and other than displacement, share nothing with the previous Vortecs. Internally they are given the Lt designation rather than Ls of the Vortecs.
Everything you said is correct except they have had displacement on demand since they came out in 2014.
Excellent 👍
Why are you not using sway bars?
What was the towing mpg?
GMC Great Matador Compilation
Good luck with channel 🙂
Thanks
Red tow hooks! Enough said. Take my money!
First thing I would change(shaking black spray paint can)
Like the looks But should come with 6.2 ✌️✌️🇨🇦🇨🇦
Always wondering how reliable the air suspensions are? Often see ppl post the suspension issue after a few winters.
All airbags will eventually leak. I have 3 older vehicles with air suspension all leak air. No matter what brand they all do it.
Where is your Weight Distribution Hitch?
Any towing fuel economy figures?
Would be interesting to know that number and see the difference on a retest when the diesel is available.
We only got the truck for the day - we too want to do more and we will as they come on fleet.
I get 6 mpg towing my 30ft 8600lb travel trailer
I read that the 2022 AT4 has the 6.2L HP available.
You went to the Tahoe RST and for the first time it looked better than the Yukon.
AMAZING ++++++++++++
Woah did you leave TFL?? You were one of my fav reviewers
Yup. Decided to come back home to TK and work with my pops. Hope you like the new channel!
AWESOME
Thanks 🤗
Diesel not available in the AT4 model on the Yukon right?
Correct.
The Chevrolet Tahoe and Suburban, the GMC Yukon and Yukon XL, and the Cadillac Escalade account for 50% of all large SUV sales in the US. GM makes 340,000 of them every year and exports about 80,000 to 31 countries. They’re made in GM’s plant in Arlington, Texas, which is said to be the most profitable assembly plant in the world. We estimate they generate $20 billion in revenue for GM and about $4 billion in profits. Autoline Daily.
Wait , the regular Denali (NON XL) has 7 seat arrangements ? No way
GM yukon needs to have the turbo charged engine, same displacement volume with a bit of a turbo to go over 450 HP. Possible? Is it possible? why not doing it?
Ask GM
No one has seen a 3.0 duramax in the SUV's yet and im itching to see one
Won't be till closer to Christmas
@@TruckKing Damn because that duramax will complete these suvs in my opinion
How much tongue wait can this Yukon handle and how much does this trailer have?
I noted this same thought about. This Yukon had a max tongue weight of 810 lbs (shown on the sticker below the max tow rating he points out in the video). I did the math and at 7600 GVWR of the trailer is too much for the Yukon. Dangerous.
Would just like a 2500 suburban.
With an actual locker.
And in diesel...
Can u get this or the tahoe on the hydroline?
Never say never - we'll see
This is the way to test vehicles that can tow. We look for videos of SUV's like this to tow a TT not a flatbed.
Aircon surcharge? Bi weekly payment calculation? Are bi weekly car payments a common thing in Canada?
Yes, in fact most dealers advertise their prices that way. Not a fan.
@@TruckKing Glad I tracked your channel down after you left TFL. Keep up the good work.
Just curious about the differences between the Z71 and the AT4 again, you stated that the one gets the G80 and the other gets the ELSD. If you watch this video there is no locking of the rear diff.? czcams.com/video/Ft9jOZfZHXE/video.html (7min) I asked your old Co-worker (Andre S) about this and he mentioned that apparently it was faulty and that both the Z71 and the AT4 get the ELSD. I'm disappointed that these vehicles don't offer the rear view camera in any trim other than the High Country/Denali seeing as how large they are. We are looking at getting one of these for our growing family and I've been doing as much research as I can but still confused as to why these things are. Also how is it that the similar equiped suburban is 8K cheaper than the Yukon XL? HUD, leather quality, better differential? Thanks for any clarification
This requires some investigation - when we did the original drive we were told one had the G80 and the other didn't. Then they said they weren't sure after all. We'll make some calls.
GO GO ++++++++
i would like to have seen you get that short wheelbase truck on the highway with no sway control hitch. not real safe. Talk about white knuckle.
There were multiple questions inquiring about fuel economy while towing, but none were answered. Is it that bad, or....
On short test videos like this (less than 75 miles) we don’t measure fuel economy. Would not be a fair average.
I don't understand how the trailer blind spot monitoring works?
GM's site has a good explanation - google it.
Vehicle reviews have never been so therapeutic before.
How come this SUV does not come with tow mirrors when you have the tow package...that is really weird IMO. Nice SUV but I am skeptical of long term reliabilty with GM.
These SUV's time and time again can make 300,000 with not much money outta pocket. I use suburban and Tahoe for my business. And I have no complaints
Highway Traffic Act (in Ontario anyway) says you have to see clear down the side of the trailer.
Take your dad to work day lol
I don’t think you could get the 6.2 with the AT4 package... at least, not according to the GMC configurator.
You are right.
