Testing A New GMC Sierra 2500 Denali While Pulling A 14,000 Pound Fifth Wheel Up 6% Grade With MPG!

[@fredengelage435]

Just did a 8,000 mile RV trip to western Canada and USA. The most popular truck by far in all the RV parks was the new GM diesels. It used to be Ford and Dodge but not anymore. In talking to the owners, they all loved the power of the Duramax and the smoothness of the 10 speed Allison. GM seems to have hit a home run with these HD trucks.

[@Jassman3536]

I have had all 3, love them all for diff reasons. What I notice on my 20 F250 with the stock bed cover is you can lock it in any place and the drain tubes go out the front wall.... this way I can slide plywood all the way in without worrying about kinking the tubes. Keep up the great reviews

[@TheRoeshow0324]

I love my 2021 GMC 3500. I think for people towing 5th wheels just get a 3500. Not necessarily a dually. Just get the added payload. The price difference is minimal. I went with GMC for the independent front suspension but all the HD trucks are great

I’ve had diesels from all 3. Cummins exhaust brake is night and day better than the gm and ford. For me the exhaust brake is a huge advantage when towing heavy through the Rockies. From a safety standpoint I would choose the Cummins all day. Power wise they are all very powerful setups and will each do the job in that department.

When GM came out with the steps I made fun of how ugly it made it and now I don’t know why others do not have them. They are very useful! Fuel mileage is only about 8 mpg more on average running at around 78 mph on cruise. But if you run slower speeds your mpg will be way more.

@@tylerking27 that’s true on age and short box but if it was up to me I would have bought a 2007 5.9 cummins six speed dually like I had back in my younger pipelining days. How I miss manuals in my trucks. I’ve been in new Fords and they are okay. We had a bad experience with our hometown Ford dealership so between that and the 6.4 exhausted me on keeping up with it so I would not end up on the road I will not buy another. I’ve owned (2) 5.9 Cummins six speed, (1) Powerstroke and now a Duramax in this order. As for new stuff these days, they are all pretty much the same. Built American tough with Foreigners stuff. When I wrote this I was comparing the Duramax to our Powerstroke pulling our 7,500 pound travel trailer. But since then our Duramax is now a hotshot truck and I have a Cat Scale ticket that I ran a load at 38,400 pounds and the Duramax didn’t break a sweat! That’s truck, trailer and load combined weight. We all have our reasons why we drive what we drive!

[@ronbennett6083]

Great video I have a 2021 GMC Denali and towed a Grand Design 28BH. I added the Firestone airbags and added 25 PSI to each side. The towing experience is amazing. Prior to the airbags the truck was squatting about 3inches. With the airbags we are level and the ride experience great.

[@richardmathern900]

if your truck is squatting your load set up is incorrect. Just a huge fyi. You fix that and you would be amazed. Really simple actually. A squatted vehicle towing really shows inexperience in towing anything.

Hey JB. I went back and forth for months between this truck (1 ton) and my Ram. For some reason the Ram just felt better overall and had a 10x better interior especially with the mega cab for me. Where Ram falls off is the different rated Cummins engine transmission combo. If they had mate a HO Ram with an 8 to 10 speed Aisin, I think they win the hands down. We will see what 2023 brings for Ram. Thanks for the video.

[@easttexasengineering3489]

Good video. Your 100% correct, the GM exhaust brake is nothing and barley aids the truck in stoping. Ram hands down is #1. I drove all 4 HD trucks (4th being TitanXD) I settled on my 2021 Ram High Output dually and it WILL STOP my 14,000k load on exhaust and engine brake by itself.. people who never been behind the wheel of a Ram, don’t know what they are missing. And I honestly would take my Aisin tranny over the Alison too. I agree the Alison shifts better but I know the Aisin reason for hard shifts is saving the converter. Both good, but just my preference now. You have fun with the Fam brother..

Inline 6 cylinder diesel engines have better engine braking by design. As a truck driver I've driven them all at some point over the years. I'm a Ram Cummins guy, but I would seriously consider one of those GMC's as my next truck!

[@brad2361]

I just went from a 18 Ford to a 22 AT4. You will regret it. Don't listen to the hype. My GMC pulls my 5th wheel ok but it gets 7.5MPG compared to the 11+MPG my Ford would get.

[@czwarlord9243]

GMs are nice riding trucks and have fantastic interiors no question. Definitely smoother than the ford and the rams. However the big killer for me on the ford and the GMs is that poor excuse for an exhaust brake. It really is a big deal towing heavy through the Rockies. There is a reason why the majority of the hotshoters drive the ram. Although there are some things I admire on the gm, I won’t give up the exhaust brake, and how much easier the Cummins is to work on. Get gm to fix that exhaust brake and I would prolly come back to one.

[@B-rad303]

You need to go downhill with the exhaust brake on. The truck has a tilt sensor in the computer. I tow RVs for a living and I can tow a triple axle 42 toy hauler down Eisenhower in Colorado. And it holds what ever speed you set the cruise to no problem

Nice video. Good to see the family with you. I think the Mrs. was a little worried old Justin was wanting to trade 😂😂. I’m with her on the $82,000 price, wow. Looks like the truck did good. That one had a slightly lower payload than most will have but it was probably fully loaded. I think if I ordered a new diesel I’d go ahead and get the 3500 SRW if for nothing else to get the physically bigger ring gear and overloads. I still say you are secretly wanting a GM lol.

[@JB_WhoWork]

Haha! Yea I really like this truck and it does have the best exterior design. I second the 3500 just for the extra payload but man the exhaust brake is a killer. If it has stronger downshifts I think I could live with it but that’s not great either. If I ever come up you way, I will let you test my setup 👍🏾

[@matthewanderson9912]

@@JB_WhoWork I agree the Rams have a better exhaust brake. GM wants you to use cruise and then also really get on the brakes to get the truck to downshift. You do that and they will lose speed even on an 8% grade. Low speed maneuvering though you definitely have to get on brakes more. I think that’s got as much to do with engine design as anything else.

[@bg5561742]

I have a Chevy high country with all the same bells and whistles I love it I pull a toy hauler with my 4 seater rzr in it

[@ImYourHucklebery117]

We have to keep in mind that this generation of gmc/chevy, the gooseneck is a couple of inches behind the center of the rear axle to give a greater clearance to the cab of the truck. Normally it should squat a little more than ram or ford

[@brandontuckett767]

If the gooseneck is behind the axle it would squat more not less

[@zachdemand4508]

I have a 2012 3500hd with the duramax. When I use the exhaust brake in tow mode all i have to do is give it a little bit of brake to get the exhaust brake to engage. As soon as the exhaust brake kicks in it stops quickly. Just letting off the gas will let it coast until it get to 40-45 mph then the exhaust brake kicks in and slows it down fast. Just tapping the brake at 70 mph isn't going to do anything, you have to give it a constant petal. It doesn't need to me much, just enough to let the computer know you need to slow down now not just coast. I think if you had time to get use to the truck, you would want any other.

My 2020 Denali Dually pulls a 22k 5th wheel perfectly. I would think driving 75 mph is a little much while pulling. Stay safe!

[@JB_WhoWork]

Thanks, it’s hard to beat the RAM’s Powertrain, especially the transmission/exhaust brake. I find that RAM does have the better stability but this is dependent on tires. Ford performs equally well but all 3 will get the job done with minimal fatigue 👍🏾

[@JohnDiMartino]

@@JB_WhoWork Only if you step up to the 1 ton and get the HO. Rams are so payload limited and both 6speeds are just holding the Cummins back. The Ram2500 is basically a bumper pull only and grocery getter. My half ton has more hauling capacity.

[@adamgrossman8715]

The reasons commercial companies buy trucks is far diffrent then why people who use them for personal use. One of the big driving decisions on buying a truck is service centers. When it comes to rams and the Cummins there is no equal in terms of service centers. Every ram dealer can work on cummins, every cummins dealer can work on a cummins, every heavy duty truck dealer is also a cummins dealer. Meaning you can get parts and service almost anywhere which is why the ram trucks are so common in commercial applications.

You having a dodge truck you may not understand how to set the downhill speed hold. You have to use the large button on the right side opposite the exhaust brake switch. Two separate operations on the GMC you can use the exhaust brake to help normal braking or the downhill speed hold when driving on long steep downhill roads.

Look at you showing the love to GM lol. You need to redo this test with a 2017 - 2019 model year with a diesel and the 6spd. I had a 2017 and 6spd and thought the diesel brake was quite effective. It’s possible with all the extra gearing it’s not as aggressive now. Only you can find the answer.

It is not an Allison transmission. Chevy and ford built the transmission together and had Allison engineers look at the transmission. Gm asked the Allison engineers if they could put the Allison logo on the truck. Allison engineers said ok . I know a few people that bought gm trucks and they were told they are not real Allison transmissions

[@andyjohnson6742]

Ford has nothing to do with the Allison branded 10 speed HD transmission. Gm builds it completely with Allison’s specs, Ford and Gm co-developed the 10 speed for 1/2 ton trucks and some cars aka the Camaro and mustang.

[@denistaramasso9724]

Also the 3/4 and one ton got this from a friend that works for Allison. Why would you go to your competitors to help you build a transmission when gm once owned Allison. I lost respect for gm .

[@beaus3472]

Whoa. JB might 'jump ship to GM'? Has the world gone crazy?? Seriously, thanks for another great video, and look forward to seeing your new Dmax, lol.

[@JB_WhoWork]

🤣🤣🤣 thanks bro 🤣

[@hausmanaaronw]

You can get a brand new one from Laura Buick Gmc for$ 78,715. I don't understand why these used trucks are more than new?

[@twatsonr1]

Because you can pick it up right away. The order time for this truck I’ve heard is around 6 months

[@hausmanaaronw]

@@twatsonr1 my buddy just picked one up. Was told 6 weeks plus on wait. Got it in 6 days.

[@Evilsapper]

WE are getting a 2022 GMC 2500 AT4 Diesel. Was wondering if you have done a video hauling your 5th wheel and if you had any problems? Thanks in advance.

[@JB_WhoWork]

What kind of problems?

[@Mike-xo3fi]

Nice video!! What’s the pin weight of your trailer and dry weight? Thanks

[@JB_WhoWork]

The way it was in this video was 2680#’s pin and dry it was 1980#’s

[@sheepledtotheslaughter4917]

No turn test?

[@tylerdunn6578]

Upgrade on fuel system might compare to a ford

[@chadmiller6487]

I know one thing. My 23 3500hD rides way better than my 20 f250..

[@jonnyg44]

Hoping you could help me out or some people who read these comments. My work needs a tow rig for between 10k-15k lbs. it’s portable stage. Would be towing around md so not many mountains, my thoughts were f250 with the 7.3, I figured gas in case someone was driving it(besides me) and would forget to put diesel in it

[@EBKRV412]

It will outperform both in the 3/4 ton diesel segment on paper and at the scales no matter what with GM having the higher GVWR over Ford and Ram...GM gives you the OPTION to downgrade to a 10000lb gvwr as of last year ford does have a higher payload gvwr capacity option now on the 3/4 ton diesels...but nothing for ram...Ram is really behind the times in the GVWR game and cab size game for sure...for those 2 reasons I'd never spend the $ on them right now

[@JB_WhoWork]

Yup, GM is really putting in the effort to beat the other two and it shows with a larger short bed, moving fifth prep behind axle and GVWR increase 👍🏾

[@JT-lu8vt]

The sway your talking about do you think it’s from goose ball or do you think it would still have a little sway with conventional hitch

[@JB_WhoWork]

Good question, I wouldn’t suspect sway from my setup being a gooseneck but I would have to switch to a fifth wheel hitch/pinbox to compare

[@Em_jiggy]

@@JB_WhoWork that would be a good video! You do great on the truck videos, so if you had a segment in hitch comparisons it would be so good for the channel!

[@mohammednuredin4663]

The new powerstroke out pull both duramax and Cummins

[@TrumpWon45-47]

I love the power stroke but man your comment is fake news.

[@RobinHoodTexas]

I'm just now researching rv's and am curious what is the "6% grade" setting you did?

[@JB_WhoWork]

Hey Robin, I went up a 6% incline on I70. The test was to see if truck would maintain speed and/or increase it 👍🏾

[@NicktheStumpGuy]

Man that is a nice truck! I just still can't believe how far behind GM is when it comes to interior. That screen is puny!

[@slimlight5786]

If I lived on a Cul-de-sac and just towed RV's I could see why people would buy GM.
