GMC Sierra Duramax Diesel vs Ram Cummins HD vs World's Toughest Towing Test

[@TFLtruck]

[@bigbossman5969]

its funny how they made a big deal about vw and ram trucks putting out 2 much pollution and fined them big time but they let this company make these trucks called gliders. its a new truck with a older rebuild diesel engine in it they don't have emissions controls on them because of the loophole. in the law. how fare is that. people look them up.

[@rodleypumpkins4174]

Look you guys are nice enough but you are not even using these trucks how they were designed in these scenarios. Your passing off your “stress tests” to people who probably don’t know any better. Also it was hard watching you two with the tow hooks Jesus it was sad.

[@beunbad]

@@bigbossman5969 because all the emissions on big trucks ruin the motors and cause a lot of downtime. And I think the older motors particles are bigger and fall to the ground where emissions trucks atomize it and put it into the air. Down time fixing emissions trucks cost truckers too much money and can ruin a business that’s why they buy Gliders.

[@ronfeinberg]

Gentlemen, if I may add my 2 cents. I'm on my 3rd Duramax (15, 16, now I own a '17 L5P). I don't believe you fairly tested your Chevy in the downhill/braking portion. The correct method for going down a long steep grade is to have the exhaust brake engaged while using the cruise control to adjust speed. The computer will then control the variable vanes of the turbocharger to achieve the desired speed set by the cruise control. I have traversed many times the same sections of i70 through the tunnel where you perform your tests. I am always amazed how well the truck goes downhill; I often use the term "hand of God" when referring to how the truck responds when I tap down the cruise control to go a few miles/hr slower when confronting the twists of the same road. I never need to apply my brakes, not once. Often I talk to Duramax drivers at campgrounds who don't know about this simple procedure. If I may make one other comment. The Ike Gauntlet while being an extreme stress test for trucks is not indicative of how trucks perform while towing on 99.9% of North American roads. Here's my case; last year I bought an '17 F250 to tow my TT. I live in the North East where mountains are less of a concern than out West. However, while towing 10k the F250 could not sustain the set speed on cruise control on even the smallest of grades. If set at 65mph, the truck would slow down on an incline to 61-60 before downshifting to 5th, then race up the hill, eventually speed past the 65 then upshift back to 6th gear. I kindly refer to the Ford as having a lazy cruise control. This is real world driving that no one on KZbin tests. I sold the Ford 2 weeks after, and returned to my Duramax's. The Duramax at most will lose 1 mph up hills and rarely needs to downshift. This post is not a poke at Ford, but a request to conduct tests on how trucks perform how real people use them, not just a stress test. You guys are great, and I do appreciate all the effort you put into them.

[@Kylewatchesstuff]

Didn't they downhill test the Chevy 3500 using cruise control? They loved it then. I love the functionality of using cruise control and the exhaust brake when hauling horses down the grade on I-77 in VA/NC (which is about 7 miles) it performs like a champ and the speed remains constant. I don't even have to hit the brakes...They missed this one....

[@barrthom603]

You had a 17 F250 with the 6.7l powerstroke? How did you like the new superduty vs the 17 Duramax?

[@ronfeinberg]

Barr Thom I liked the technology of the F250 but not the feel of the solid front axle. The worst was the lazy cruise control that couldn’t keep the set speed while towing on the smallest of inclines. That was the deal breaker for me. Sold it after 1 week.

[@truckpette]

Exactly, that is how this engine works. They are similar to how the Detroit Series 60 motors in semi trucks work with cruse engaged when climbing a mountain. And, yes, if these gentlemen would understand that as a Duramax engine works they are standard with engine braking technology. Therefore, on a downhill application, on Donner Pass where this was filmed, the engine brake would slow the truck down, and a heavy brake application would not be necessary. I have a 2006 GMC 2500 HD with the LBZ Duramax, and that is exactly how it works. Love this pickup truck to death with the engine braking capability. Keeps me from having to hit the brakes.

You also have to take into consideration the overall quality of the truck. I owned a 2014 ram 2500 Cummins and in 4 years there has been over 8 recalls on the truck/engine. Plus the Allison trans will last way longer. For these reasons I made the switch to GM.

You even said in other tests that different trucks have different methods of doing something, you even said in this or another vid where you compared a Dodge to a Chevy or GMC that the exhaust brakes WORK DIFFERENTLY, but you chose NOT to PROPERLY use the GM's exhaust brake...a bit of bias?

I'm a born and raised Chevy guy, but all 3 trucks are badass and have their own ups and downs. It's 100% personal preference honestly. Besides stock power is so restricted with EPA bull shit now days. Delete kits, exhaust, CAI and tune really wake these engines up and make them beastly trucks. Were talking about 200-300hp/tq gain EASY on mild settings for all 3 brands. That's badass if you think about it. Stock is lame for old farts lol I get keeping it stock for warranty purposes, but in reality all 3 stock will basically perform the same or close to each other at least. Again pick what you like best, I would buy a Chevy, but that doesn't mean the Dodge and Ford are not super nice and performance/towing beast.

I use the cruise control, no brakes needed. Lots of steep passes all over Colorado. I can't think of one pass, where i the exhaust break is not sufficient. In my opinion, you guys are not properly 'driving' the truck. Thank you for the videos and reviews. very appreciative of your efforts.

[@Perry-ck1hv]

After 4 super Duties of varying engines I got pissed I went to buy Chevrolet in 05 however they changed to the ifs suspension I'm not having it, I went and bought a Ram 3500 with the Cummins 4 by 4 I gotta tell you I truly love this truck after 13 years of ownership I replace the serpentine belt and a water pump other than regular routine maintenance I use Lucas injection cleaner exclusively as well as Lucas Oil stabilizer with my Rotella oil this truck has never let me down and it pulls 20,000 pounds on a regular basis I guess I'll keep it for another 13 years.

[@toughbowtietruck]

So you're telling me an engine brake designed to slow the truck down is getting bad remarks for actually slowing the truck down well? The new brake is calibrated with the cruise so unless cruise is on it will slow down aggressively. And why are you making a scene over the trailer hitch? It is the same style hitch that has been out since at least 2015, maybe even 2012 when the frames came out. You never seemed to have a huge complaint before. These videos are starting to show bias and it's not good.

I also don't think it's fair to test an off road truck like the All Terrain X against a regular truck. The GMC has off road suspension and tires so it's tow capacity is limited.

Pretty hard to argue the results. The GM does in fact look like the big brother of the Honda ridgline, the rear end gear ratios weren’t even close, ram was down on power compared to the gm but was still quicker, .1mpg difference could well be in the computer and I’m surprised they didn’t actually use the fill up method to confirm mpg. The fact that a HD truck can’t get a hitch that will accept your basic safety chains is completely unacceptable-I totally agree on the subjective scoring on that point. Looks like gm is slowing going away from making an actual useful practical work truck and catering to the grocery getters of today’s generation. From the solid axle, to the simplicity of an inline 6, to a masculine truck design, ram has it covered. Sorry GM fan boys lol

[@yoddy0]

I found it pretty impressive that the gmc with that dumb back rack for lights and those A/T tires did that well on MPG even with having to brake and speed up more then the ram.

You must be dense..... They applied the brakes... It slows down. They let off the brakes. It keeps slowing down(automatic engine braking). Which is common for new vehicles, the GMC just did it WAY TOO MUCH, to the point it wouldn't hold speed, but would slow WAY down.

They have the manual shift feature for a reason, find the gear that works and use it, don’t go stabbing the brakes and then hitting the throttle going down hill.

I love your videos guys. It looks like a lot of fun to do. I noticed that you guys concentrate on the most powerful engines available. However, I know for a fact that a good percentage of trucks sold in Canada and the U.S. are equipped with the base engines. I have a 2015 F-150 Super crew 4x4 with the base 3.5 L Ti-Vct engine. Never once have I ran into a lack of power. Now, I don't have anything to tow but I do haul junk around without a problem. I would love to see what the base engines in these trucks from Ford, Ram and Gm can actually do.

I like all trucks. In my opinion the 2500 series world is an 80 20. that meaning 80% empty 20% towing /hauling. the Dodge, suspension wise is built heavier than the Chevy having a solid front axle but again for 80% of the time riding empty or lightly loaded a softer ride would be more appropriate. also the Gm cost more up front but holds more value in long run. that all being said I bought the Gm and am very happy with it all around. if your towing or hauling more than that 3500 series and up is more appropriate. again my opinion. thank you Fast Lane Truck for your work and dedication.

[@therealjohnsmith4811]

Why? Gas mileage is affected by gear ratio. The test is impossible to do with an apples to apples comparison. Its completely unscientific to do the tests under differing conditions as well (different time of day). There is no "winner" or "loser." They both did what they are advertised to do.

[@profjohnfrinks]

I have not driven a Cummins but have an f550 powerstroke dump... just as a disclaimer. I have this exact Sierra(I removed the cheesy bar). Really, it is a modern marvel. Especially the downhill speed control. You really just have to know how to drive it. Basically, you press the brake once, the truck will downshift, and then you can keep an exact speed just by easing on and off the throttle. If you do not give it throttle it will almost stop, at full towing capacity! The safety chain hookup IS stupid, I rigged some chains and resolved that. Overall I think it's an amazing machine. I prefer it to the powerstroke. Can't speak for a cummins.

[@SF-fm7ov]

In the 2017 GMC HD vs Ram vs Ford test at11:09, Kent said about GM, "using the grade shift, the exhaust brake, and your cruise control if you use the cruise control, and it will just lock on. You don't even touch the brake." Since you don't use CC in your tests perhaps at least making this statement in the downhill analysis somewhere would keep viewers from mistakenly thinking that GM's exhaust brake doesn't work very well. Obviously, it does.

Yeah, that's their idea of "professional grade". LOL. Their engineering has sucked since they went IFS in 1988. They've never recovered.

[@markc3341]

Hence why you delete

[@supporterofsanity]

Yep exactly why I didn’t choose a GM product after owning them for 13 years. And the GMC is only rated to tow what a half-ton can.

[@therealjohnsmith4811]

Oh yeah, the Dmax is great - sure- www.duramaxhub.com/duramax-problems.html

[@therealjohnsmith4811]

RPO LB7 (engine code "1") was first introduced in 2001 and continued until early-2004. It is a 32-valve design with high-pressure common-rail direct injection and an experimental composite design cylinder head. The most common issue with the LB7 is injector failure, so common that a special policy bulletin was issued (#04039B). Fuel leaked and entered the crankcase, causing oil dilution. Early on, customers came forward complaining of severe overheating, and in some situations, blown head gaskets. Initially GM denied it was a problem, but after being sued by a consumer group, GM relented and included overheating and blown head gaskets as a warranted item. en.wikipedia.org/wiki/Duramax_V8_engine

[@tomdawson4134]

Don't even need to watch the video, go to the comments and find out who won! Quite obviously the GM won, the RAM fan boys are trying to measure their dick sizes as we speak! But ; TFLT you guys need to go into these comparisons with an open-mind, and not be biased at all. I know both these guys prefer Dodge and Ford over GM. Which is typical, perhaps they are being paid? Unsure. Rule of thumb though ; You cannot give a truck a poor score because of the hitch, that is just flat out stupid. I have zero issues with my '16 Duramax, and watching how you were trying to install the shackle onto the hitch, well. You were acting like my 3-year old when he helps me hitch up my travel trailer.

[@TFLnow]

You should probably watch the video again for the results. we are not sponsored by any of the vehicle manufacturers.

[@Eeaotc02]

Tom Dawson Sounds like you're the GMC fanboy mister.

[@dcourson7274]

Tom Dawson u do know there is a Chevy ad with howie long in it and they have TflTruck logo in it and mentioned their results from testing look it up be warned though it’s hard to watch lol

[@therealjohnsmith4811]

Nova Man Spanked? Lol- 2 seconds (give or take) and .1 better mpg. Ok sparky.

[@843MudMafia.]

The ram better it no need to get mad Cummins are use more

[@robertclark5773]

Why do you guys never feature a G56 6 speed manual transmission in any of your videos? You can order them from Dodge.

[@trailblazer632]

Try turning the hook around and going point first through the smaller round hole lol. Thats how youre supposed to hook safety chains anyways.

[@wildbill23c]

Could you do a similar test with the RAM Diesel with manual transmission? Would be interesting to see the difference in times.

[@odertube]

Your testing is far too subjective to human error. You should always be using cruise control at the speed limit. If traffic is an issue, go at different times.

[@9feetup598]

Going down grades is the l5p strongest asset. You guys need to review your technic for a zero brake application down steep hills.

[@jamiehage1839]

I-70 east out of Summit. Great test location. That is a hell of a climb.

[@michaeldrews4901]

I think you guys should try and come up with a different test because the trucks are so evenly matched that anything could cause a few second difference. Thanks for the videos guys

[@christopherking2012]

Was grade braking activated? Hold the tow/haul button down for a few seconds to turn it on/off.

[@wyo1446]

Tweedledee and Tweedledum. Lol.

[@RobShutt357]

TFL, educate your viewers by explaining that Dodge no longer brands trucks. By reading comments all the know it alls don’t know that little fact.

[@mohammedtoure3968]

Why can't the 6.6 duramax in the 3500hd pull as much as other heavy duty trucks ? it has around the same power. It's conventional towing is on par with the other trucks , but not the gooseneck or fifth wheel, which is only around 23,000 pounds, while the Ram 3500 and F-350/ F-450 can tow over 30,000 pounds ?

[@jaybrown29]

I have 3 of these trucks a 2014 2015 2016. I had to us the grinder on all trailer hitches in order to put the chains on.

[@NordicNevs]

I hate to agree with you Nathan lol but on the hitch I do. I ended up buying a new hitch for my truck at the GM factory one was garbage. Also it’s interesting how my 2015 2500 has a max tow of 17500# and this one has a max of 13000. That low number is useless to me. I won’t be buying a new GM any time soon. Great video and good work taking a hard line on that.

[@tacopro218]

I believe the lower tow capacity is due to the fact that the GMC is the off-road version.

[@jpatt973]

C Nevs I have a 2015 2500 HD Duramax Diesel Chevrolet the tow rating on it is 17100 lb gooseneck 5th wheel and 12000 lb off the rear tag hitch I think you just have your numbers confused.

[@NordicNevs]

Taco Pro it’s possible. I know there was a recent drastic cut. One of the previous IKEs they ran with the goose it was in the 13k range.

[@NordicNevs]

like a rock that’s what I was getting at. Our 5er/goose was in the 17s and conventional at 12k. The video posts max towing numbers as the Ram had 17xxx and the GM 13,000. Disappointed in those numbers. Just weird how our trucks are the same (15s) as the new ones (17+) with the exception of the power plant, yet the sharp decline in reported towing numbers is present even with all the engine upgrades that were made. Alas. I’ll keep my 2015 lol

[@jpatt973]

C Nevs I'll stick with my 2015 to cuz I never want to spend that kind of money on a truck again lol

[@montanawild7558]

You scoring is so flawed lol, every time I watch your videos I just shake my head

[@KErtter1]

There is too much bias in these tests... they spent so much time talking about the Ram and NO time talking about the GM. Scoring the truck based on a hitch application is inaccurate as well, since that can be changed.

[@KErtter1]

You guys really need to run these tests multiple times and take an avg to avoid having traffic slowdowns and other inconsistencies.

[@justfloorithair7155]

The Fast Lane Truck it's not that hard to figure out how to get those hooks in the holes. If you put it at the right angle it goes right on. I wonder how well you guys would do on a kindergarten shape test

[@trailblazer632]

They put the safety hooks on upside down and backwards lol. This is the shit that scaree me with people towing heavy loads. "Points down" is the proper hookup method. Had they pushed the hook points through the small entrance hole and out the side cutout the hooks fit perfectly fine. If your hooks point up and your safety catches fail your hooks fall out of the freaking hitch lol

[@nwedrick]

So let me get this right, in a downhill test where brake fade and runaway vehicles is a big issue you downgrade a truck that downshifts and slows you down with little braking. How is that anything but a plus cause you know you can slow down and come to a stop if you need to and you're not going to overheat your brakes. That should have given it a better score.

[@k.r.v.4219]

In the GMC going down hill the grade braking works best with the cruise control on! Hey Nathan! It is NOT the trucks fault the safety chain hooks are too small!!! But if the two? I like that Ram best! As much as I like that Blue in the Harvest Package, the beautiful Brown Frost Beige Interior color is not available with the blue or harvester red, you get stuck with the boring black! Mine would be a Laramie in Pearl white and the brown Frost Beige Interior! It’s too bad cause I like that Blue!

[@claytonblachly4031]

K. R. V. There is always Black Forest Green

[@NathanDAdlen]

Well, I fault the truck-maker for selling a vehicle that doesn't accept a standard-sized chain. I agree with you about the Pearl white - it would be fantastic on the Ram. Thanks for watching!

[@k.r.v.4219]

Clayton Blachly that’s true and is also a very nice color! But I’m planning on moving to Florida and would rather have a light color due to the strong sun.

[@k.r.v.4219]

nathan adlen standard size chain for what? When the hitch they provide is rated to a higher standard!

[@justfloorithair7155]

nathan adlen The Fast Lane Truck it's not that hard to figure out how to get those hooks in the holes. If you put it at the right angle it goes right on. I wonder how well you guys would do on a kindergarten shape test

[@sticrzy123]

Love my 2015 6.7 Cummins

[@cbull316]

I would totally agree with you on the safety chain loops in my opinion it's a very stupid design and I do believe the new Fords have got something similar which is also aggravating. Curious why you didn't use the higher horsepower Cummins option When comparing it with a newer higher horsepower Duramax? The ram equipped with the aisin transmission would have been a better comparison to the new Duramax, in my opinion.

[@gabehatfield697]

“So despite Duramax being better in every way I’m giving it a lower score”

[@calebniederhofer678]

GABE Hatfield Cummins is hands down the best engine available, but as far as a overall truck that’s subjective . I would say ford , although looks like ram completely just knocked it out of the park with the 2019 !

[@calebniederhofer678]

chuck koscinski the 6.7 uses over 40% of the 5.9 . That’s cool its all preference , but from a reliability , economy , towing stand point Cummins is better . It’s the only commericial rated medium duty engine compared to duramax and ford who are both a light duty engine . V8 produce a lot of torque but at a much greater curve they don’t have the same low end torque Cummins produces at low rpms

[@WilliamStewart1]

Caleb Niederhofer That's incorrect, ever since the emmisions were put on the 6.7 it's been a disaster. I know many people who are always having issues with thier 6.7's including myself. The 5.9's were gems, but the 6.7 is a far cry from it. Realistically if you look at it right, since emissions have come into play, the Dmax has been the most reliable.

[@calebniederhofer678]

William Stewart lol all of the diesels after mid 07 have them . I never once said , dpf is not a problem I hate it like everyone else . Cummins is the best engine as far reliability , maintenance, towing . You are going way off what I even said lol

[@calebniederhofer678]

You are not making any sense , current diesel to current diesel is what I’m talking about . I’m not comparing a 2018 to a 5.9 or 7.3 as far as reliability of course , less emissions is always better . Engine runs cooler , better mileage .

[@jeffthompson9589]

These guys don't know there ass from there head. Smh

[@Brandon_Mo]

dmax junky but I bet they know their from there

[@Hudbri11]

The fact that a 3/4 ton GM Diesel has a max tow of 14,500k lbs in a LTZ/SLT platform is sad when a 1/2 ton GM with the Gas 6.2 has a max tow of 12,500. I wanted a L5P until I seen the #’s on GM’s website. I will be sticking with RAM!

[@XShadowHazeX]

GMC makes nice trucks, but I'd have to give Ram the hand for towing. That Sierra looks sharp though. 😊

[@kirbygoodwin7133]

Use cruise control people, it wouldn’t require anything. And that should be allowed since that’s what normal people would use

[@therealjohnsmith4811]

So a computer difference of .1 mpg and 2 seconds (give or take right?)? So basically even and no clear winner. If you had a heavier trailer you may want that GM engine brake. Chain hooks? That's a $100 fix to get larger hooks that you could have gotten with the trailer when you bought it. You subjectively nit picked for things that aren't really a problem or lack of capability. No added points for no need for a weight distributing hitch for the GM and Ford. New safety hooks are cheaper that a weight distributing hitch.

[@sabanite08]

The Real John Smith full of excuses

[@xQuantom]

And the bigger kooks are safer. And for all we know the gmc could have went faster if it weren't for traffic making him guess the time

[@therealjohnsmith4811]

Excuses? Lol. I lean toward Ford; but, I'm also about fairness and objectivity. I'm sorry common sense and statistics escape you. Subjective scores should be based on real shortcomings. Is it the truck manufacturers fault for not conforming to the trailer manufacturer or vice versa? Maybe the trailer manufacturer needs to update their tow hooks to accommodate newer trucks. An exhaust brake that works too well? Oh, the horror...... Do you know that they even used it correctly?

[@baseballwarrior17]

Can't really have a heavier trailer when the test trailer is 12,500 lb and the GMC's max towing is 13,000 lbs.

[@therealjohnsmith4811]

14,500 for conventional. - 17,500 for gooseneck/ fifth wheel. www.chevrolet.com/content/dam/chevrolet/na/us/english/index/articles/truck-life/trailering-and-towing-guide/02-pdfs/bb-quantum-trailingtowing-printablechart-silverado2500HD-020917.pdf

[@moserkm]

I'd like to see some fifth wheel testing. Towing a small but heavy trailer is one thing. Towing the same weight in a 13+ foot tall trailer is a whole different deal. Please test the big 3 duallys with 16,000 lb fifth wheels.

[@wilbready]

You mentioned only one brake application in the Ram coming down Ike, but did you have the exhaust brake feature on? Curious minds need to know!

[@abduallahalkhateeb9659]

i have a question at the minute 6:47 the worning label theres some arabic works how is that?

[@abduallahalkhateeb9659]

holly shit i meant arabic words how is that possible if the car is sold in america

[@michaelpincavitch6525]

The gmc had 373s with more hp. Ram had 342s with less hp. Ram is the only one you can get a manual trans in , which a lot of people prefer ! But I'd like to see the ram and the gmc in another test with the same gear ratios in both !

[@justinwaite26]

...thats why I've suggested several times..set the cruise to 50mph ..the truck will adjust itself for downgrading...if then you have hit brakes..take points off

[@swss12]

for the chevy emergency hooks, just install shackles through the holes and leave them there like what everyone else does

[@clifdavis9013]

I don’t have an issue with the hooks on my travel trailer. I have the 2016 Silverado. While it is awkward and a strange design, the hooks do work with it.

[@dedduck87]

Interesting with the uphill you didn't have tow/haul mode on for the Ram but you did for the GMC. Not sure I understand why?

[@mrtoyotatrd6126]

I love both trucks. There both just as badass as the other one. I want both. I love the new Powerstroke Ford f250 superduty king ranch too. 👌

[@tater0909]

What's the 3 rating on cummins? How do you tell which truck is which? I know the one ton with aisin has more

[@SF-fm7ov]

I think you should make 2 runs. One downhill as you do now and 2nd with cruise on. You could take the best or average of the uphill climb as well. It is only 16-minute round trip. This would clear up some of the complaints.

[@tsyracusa60]

It’s been the same hitch for like 5 years and now it’s problem lmfao

[@MrTruckTV]

This one is a little different

[@tsyracusa60]

I can assure you that 2015, 2016, and 2017 GM hd trucks have the same hitch as an owner of them all.

[@tsyracusa60]

On all my truck I have added a simple Clevis hook from tractor supply for a cheap and easy fix. I even did this on my last 2013 Silverado 2500. You people make it sound like it’s the end of the world.

[@williamsinger4124]

Thomas Syracusa this comment needs more likes. People spend 60, 70k on a truck and that's fine. But heaven forbid having to get a couple of hooks. These days, I swear you can hand someone a million dollars cash, no strings attached, and they'll still bitch about the color of the money

[@jakecreech1659]

Of course it's an easy fix but when you spend 60k, 70k, 80k on a new truck IMHO maybe they could throw in a set of properly fit clevis'.

[@RobShutt357]

I wish the audio was better.....great video again.

[@Pru1234]

Have you guys ever considered doing some of these tests with viewer's modified trucks? Mainly to see if things like tuning, water/meth make a large difference in the results.
