Great video. I've never seen anyone do the side by side comparison to this level. It is great for people to see what works for their application, without bias. Love these videos. I don't tow a lot, so I ended up with Ram 1500 with 3.92. I got a great daily driver, and I am also confident that I can tow a full size truck on a car hauler without issue. If I was towing a fifth wheel or large box trailer as you do, I would have gone 3/4 or 1 ton. After seeing hours and hours of your tow videos, I am confident I got the right set up for me and the wife. Thank you!
Yall make a great towing team. You guys should make more videos together.
I'ma keep my GMC 3500 DRW 6.6 L8t and you can keep your diesel headaches.
You guys are having too much fun...lol
Could you do a tutorial video regarding how the trailer brake works and how you actually use it.
Also, your check list regarding prep for towing setup.
I'm new to this and have much to learn.
Thanks....
Another excellent video. I owuld be interested in hearing your thoughts on tire pressures. I see 68/74. Is this your setup just for towning? Do you run the same while solo/everyday driving? Thank you!
JB, geat video! If are are serious about testing with a diesel 1-ton let me know. I have a 2024 GMC SRW and would love to see what it could do in your test.
As far as your breaks not working right away, I’ve had the same issue. My bumper pull trailer is finicky with my new 24 GMC but my boat is fine. I’ve never had any issue with my trailer with any other truck as I’ve tested it with others having no issues. It will randomly come back on when even stopped at a light not moving then stay on for the remainder of the trip. It’s odd. The only thing I can think of is either some software issue or just on some trailer plugs, the truck plug doesn’t make a great connection. Plan on going to a different type of trailer/truck magnetic plug.
Love the reviews!!! Would like to know the prices paid for these trucks in the reviews. Great Job on these videos!!!!
Both engines are great options just depends what you need from the truck
Care to share what that would be? That is all I hear but get no real answers? I'll be towing around 8,000lbs ALMOST everyday for work in Nebraska so flat roads....What do you recommend?
@mehoff88 the gas will tow that no problem but since it's eveey day then I think the diesel is the right choice
Diesel all day@@mehoff88
@@mehoff88if it will be for work and there will be a potential for tax write offs or deductions, yes I would recommend the diesel. I own a 2022 Ram 3500 with the 6.4 hemi. I ordered the truck with the gas engine and the salesperson was shocked I didn’t want the diesel… here is what I explained to them… my wife works from home so I am able to drive her suv back and forth from my work (and I drive transport for a living and very familiar with diesels) We have a large 5th wheel trailer that we tow a couple times a month from April-May until September-October. And we typically travel 1-2 hours away to a campsite. Long story short, our gas engine truck uses more fuel than a diesel would, but very small margin for the distance we travel. Hope you were able to make a decision 🙂
You and Mikey P made some fire vids💯
I had an issue with my Ram with the connection point for the trailer plug had to get a thing of Dielectric grease and I put some on the plug. The problem was with the prongs corroding which caused the trailer brakes/lights to go in and out.
I tow a 14k lb 42’ fifth wheel with my 2023 L8T 2500. Does fine for me. In the 1700 miles I’ve towed I’ve averaged 7.5
Thanks for doing this test. For the trailer wiring, I used electrical cleaner and lube with electric grease. My lose connection issues went away.
I tired to see if you covered it in another video. Did you record / test the mpgs of the two trucks unload?
Nice video. You know I have essentially the same trailer and I have had a 2020 Duramax and now have a 2022 6.6 gas. Both similar configurations (2500 crew cab, 4wd, short bed with 20s). Over the course of a racing trip (between 180-260 miles depending on which track I go to) my diesel would always get 10.4-10.7 mpg. My gas truck always gets between 8.2-8.6 mpg. The longer trip is a much harder pull with several grades and it’s about half the elevation that you’re at (stays at 2,000’ for half the trip and never is below 1,000’). The shorter trip is a much easier pull with a lot better roads and once I get 15 or so miles away from my house drops below 1,000’ of elevation. But with that said the fuel mileage never really improved from one trip over the other.
So over the course of an actual trip, you can expect about 2 mpg better out of the diesel, grades or otherwise. So I’m not surprised by this outcome. I also want to say I’d love to see you do this same test with your fifth wheel and the gas truck and see the mpg results. I know you have pulled it but it was up that grade and I don’t remember the fuel mileage. But I’d like to see if there’s a difference between the fifth wheel and the bumper pull. Everything always points to the fifth wheel will get better fuel mileage.
Well just thinking about it logically it should be able to tow it better, the fifth wheel offers the truck more leverage to pull as well as put the weight in a different spot. It should get better MPG as well as pull better
@@bobbythomas6520 yeah. That and the way the air goes over the truck and the fifth wheel I think would provide better (or less I guess) wind drag. With the bumper pull the air is going over the truck like normal and off the back and then slamming into the trailer. So even though it’s 3’ or so shorter I think this is playing a roll in fuel mileage too.
I’ve got a 2022 Ram 3500 6.4 Hemi. Used to have a 37’ bumper pull travel trailer gvwr 10,000lbs, 11’6” high, and towed from Kingston Ontario out to PEI and towed from Kingston Ontario to Orlando florida. Averaged 26-28 L/100km both trips (approximately 8.5-9MPG) and now I have a 40’ fifth wheel, gvwr 16,500lbs, and stands 13’5” high. Hauled it from Kingston Ontario to orange beach Alabama and back and averaged 33L/100km (7mpg) I will without a doubt agree the fifth wheel tows so much better and agree that aerodynamics should help out the fifth wheel, but the height still adds to the resistance and of course the weight is a factor as well
@@BigBirdNest it’s something that I can see making sense considering the fifth wheel is up in the truck bed and that probably lets air go over it better than a bumper pull does. It would seem the air would just slam the front of a bumper pull when it comes off the trucks tailgate.
I’d like to see a test of it with similar trailers.
I think the 10 speed is a game changer for the gas motor
I am curious if the diesel was in Regen mode.
My experience on the interstate gaser is 1/2 the MPG vs diesel. Doing strictly 55 MPH roads MPGs are closer.
The 1/4 mile times seem “off”. It seems odd that the diesel, with more hp & ~2x the torque and no torque management🤨, was only ~3 sec faster. Especially @elevation. Gearing differences? Transmission programming?
If you had done the same test up over Parleys canyon (6% grade) and back, the results would have clearly leaned more toward the Diesel. The route you took on the test is relatively flat and not a real good test of the diesel's torque and engine braking. Diesel torque always prevails for towing heavy on steep accents and decants. The above said, the gas HD is very impressive and something that definitely should be considered if not towing regularly in mountainous areas or high altitudes. In my case, I tow a heavy 5th wheel toy hauler; the diesel is the right choice for me.
Yeah, see, large 5th wheel that's ALSO a toy hauler? Diesel or bust.
But for the vast majority of us weekend warriors (with maybe one or two longer trips a year) and that also use our trucks as our daily, or at least occasional family/grocery hauler, gas makes so much more sense.
A diesel for us would be like getting a Corvette for your daily commute. You'll certainly get there faster (and in style) but it's complete overkill.
I wanted to give everyone an update on the trailer brake disconnect problem. If your trailer has some sort of charging system(solar panel) etc, it will back feed to the brake control module unit and that’s why we get the check trailer warning, brake disconnect warnings. I had my brake control module replaced by the dealer under warranty and the problem it’s gone. Hope the information was helpful.
Man thank you for this video! Fun to watch the banter as y'all enjoy your toys. But the benefit is 14:10 when the data shows up!
Mikey P; GO FINS! This is our year bro!
Gm has a known trailer brake issue on 2024 hd trucks….Hopefully they are working on it
I would like to see a video of which truck breaks down first, amount of time spent at dealership and how much it would cost if it had no warranty...!!!!
Funny I had trailer brake issues with the 2024 I just rented. My Ram is in the shop, and I never had any trailer brake issues. The Chevy constantly disconnecting the trailer, and the trailer brake control was horrible when it was working compared to the Ram. I may look into this because I am heavily looking at a new Chevy.
Here in California you pay higher premium for diesel fuel and with the 10k charge for the diesel package it doesn’t make sense for that option especially when I only pull a bass boat
Crack your sunroof open while having that rear slider open. You won't have those exhaust fumes anymore.
Yep I’m happy with my 10,000-lb fifth wheel and 6.6 gas, but for a larger trailer I would prefer the diesel.
Good video! I think the total cost for towing after 3000 miles would actually be lower on the gas engine simply because of the price/gallon at the pump. Even though the duramax has slightly better MPG
Late to the party here but all new GMC/Chevy trucks require a 7 pole rv Pollak brand plug or you will get that error message. Had to replace the plug on my trailer about a year ago. When he holds the plug up you can see it is not a Pollak because the center pin is round and smooth instead of pointy.
What's your elevation?
That is in Montana ?
Great video & comparison , however for those of us looking to purchase a diesel or gas 1 ton truck to pull a trailer only maybe a dozen times a year for Boondocking & then use it for our daily driver what would your recommendation be concerning Quality, reliability & routine maintenance ? ? After watching many “You Tube “ videos of the Ford gas ⛽️ New Godzilla’s with engine & transmissions issues & the issues with diesel emissions on all new trucks I am leaning toward a gas engine with reliable transmission like the Allison . Spending 70-100 k on a new or few years older truck I want something that’s reliable , both from an engine standpoint & transmission. Gas mileage is important but I am not buying a one ton truck 🛻 for fuel savings , more for reliability & safety on towing up & down these passes of Colorado & out west . I tend to keep my vehicles forever , have a 1995 Toyota Landcuiser with 250,00 Miles but can only tow 5,000 lbs . Would buy a HD Toyota Truck if they ever built one . Thx again , luv your info & videos & content. 👍⚾️
So with the cost difference the break even point is around 200k....Does the avg owner put 200k on a truck just to break even before trading in?!?! 🤔
Does Mickey not own any shirts/tops with sleeves?
Neither does Larry the Cable Guy. He's exercising his right To Bare Arms!
@@tumbleweedking5668 lmao😂
Probably needed dielectric grease on the plug.
You think gas for towing a 10k pound 5th wheel? I am new to towing 5th wheels. Just bought a new one and now i need a truck to pull it.
I think it would do good. I’ve seen people tow way more than that. If my Ram 1500 can tow my 8400lb bumper pull the HD will pull a 10k no problem.
I tow a 15k fifth wheel with a 24 Gasser and it does great
@@Billybob501193500 right?
@@SliderFury1 yep!
@@Billybob50119 what truck are you using? I like the idea of staying with gas.
I'll just keep my good ol' 07' dmax.
General Motors needs to put this 6.6 liter gas engine in the Suburban! No @, and no cylinder deactivation makes this small block Chevy a great recipe for a suburban
I'm torn between a 2024 2500 gas and a 2020 2500 diesel... looking to tow a 14500lb 5th wheel, probably 31/2 months out of each year. Was told the 2500gas is rated for a 18000lb 5th wheel.
A 4 year old used diesel is a crap shoot. 24 gasser would be perfect
I just got a 2024 3500 with 6.6 gas. It's rated to tow with gooseneck 18245lbs so u should be fine
Mountains or flat? I have a 2017 6.4 HD RAM. My 5th wheel is about 13K it does great except for when pulling big grades mpg wise. Still has adequate power but pulls fuel down to 2-4 mpg if I try and maintain 60-65 going through V.W. & Virginia on Rt 77. Another issue is if you get a slow vehicle merging and you have to brake (urban traffic etc.) it takes you longer to recover speed and you spend fuel there. But I use the truck for daily driver farm work and it's much better than a diesel for that so there are trade offs. If I had a bigger trailer or spent more time with my RV or went out West I'd probably replace it with a Diesel. But the gasser has several advantages as a daily driver truck I'd hate to lose
@Maizevalley mostly flat areas around the Midwest, but I want to do a trip to Yellowstone and we plan on going through Tennessee at least once a year. Truck will also be my daily driver, and right not I only drive about 6 miles each way. I'm worried the repetitive short trips would be bad for a diesel.
@Maizevalley we don't camp much during the year but my wife is a teacher so we have the ability to camp all summer long. Plan is to be camping 90% of the summer.
Ive been able to get 16mpg towing an empty 20 ft trailer although it typically gets 12-14 with 10klbs or less highway of course never had a gas engine do that plus seems like it stays up to speed better also mine is only 2wd for equal power id say the 6.6 is close but beet mpgs i ever got was 12 empty no trailer either and that was taking it super easy typically it got 8mpg or less gas is cheaper though so idk id say gas 10k and under in northern states anything heavier especially in southern states diesel by far but that being said id much rathwr have ti replace a fuel pump on gas vs diesel lol
Mikey done got rid of his Ram also?
Im not understanding how the diesel MPG’s are so low. I have a 2008 GMC 2500 Duramax and have never gotten less than 13.6 MPG while towing a 7800 pound horse trailer. My average towing the same trailer over 16 trips is 14.2 MPG this is the same route in different wind and temps with 90% highway. While Im 2200 pound lighter the full economy would not be that much different during steady speeds and flat terrain. Without a trailer traveling at 60 mph I average 21.5 mpg.
Emissions are killing the diesels.
It's not the plug on the trailer. GMC needs a resistor or something. I was told it has something to do with led lights and other BS from RV dealers. Very scary seeing that warning going over the continental divide
Go Dolphins!!!
I’m sure the difference will really be seen when towing up a substantial grade and over longer distances. Also the retained value of the diesel is much higher. Still not bad for a gasser though. Good video JB.
I would hope so since a diesel is $10k more upfront. And if you’re paying interest on that it’s a lot more
@@Billybob50119thank you, the interest factor is something no one ever seems to mention. I can pay cash for a mid trim gasser but not for a mid-trim diesel. And if I'm taking out a roughly 10k loan to make up the difference, I ain't getting back the extra 2k or so I pay in interest by the time I trade it.
Besides, if you're getting the diesel, aren't they supposed to last forever? Just keep the dang thing till the wheels fall off then. Spend the 10k if a diesel is what you need and be done with it but most of us just don't need it, it's complete overkill.
@@SliderFury1 the problem is a diesel does not last forever anymore. DEF, EGR, SCR, Fuel system, emissions problems etc. Not one thing on a diesel is cheap to replace. Nobody wants them without a warranty
@@SliderFury1except they WILL NOT LAST FOREVER.
Did you say 6.4 MPG was PRETTY GOOD?!?!?
How heavy is that trailer?! I’m getting 15 mpg towing a 9,000 lb trailer with a 6.7L Powerstroke. I would personally still prefer the extra weight from the diesel to reduce sway.
😳🤔🤨
No you’re not
diesel will always be king of towing, just depends on your needs....am so far on the gas side I won't need a diesel but would in a heartbeat if i needed one...
no matter how many ways people go over this debate the answer is always the same.
I bet the Duramax was going through a regen which resulted in the low mileage. You’d have to tow for 500+ miles to get a more accurate assessment.
Yep regens happen on diesels. Yet another negative of diesels. It can’t be an excuse for mpg because they are something that happens on a diesel 🤷♂️
@@Billybob50119 Totally. Not an excuse, but if you sample only when it’s in regen, you’ll get a false average. Likely the average would be significantly higher over a longer sample mileage.
@@slidewide1999 you don’t even know if it was in regen or how long if at all…
You also got to figure in def usage so really diesel doesn't get that good of mileage
@@bigmurph1447 not towing but I just drove from Montana to North Carolina in my 2021 duramax and averaged 22 mpgs 2,200 miles. Diesel beats that gas motor in every department. Especially towing!
Once You go diesel, You never go back!
To be honest, GM doesn’t produce many gas HD trucks because they know everybody wants a diesel and they’ll pay for it. But they are right, for 90% of people who buys an HD truck they don’t need the diesel.
You know, when you hit 6 or 7 percent grades, diesel is going to beat the gasser on mpg quite considerably. Drive from Utah to Vegas and back, with both trucks, and you will see.
It all averages out. A gasser get about 2 mpg less than a diesel towing but with cheaper fuel and no def it comes out at close to the same
You know I thought all of that too when I had my 2020 L5P Duramax but essentially 2 mpg better is all it will do over what my current 6.6 L8T gas truck gets. Same trailer, same routes and me driving.
My roads on a 260ish mile round trip from East Kentucky to East Tennessee are like a roller coaster and especially the first 50ish miles. There’s several 6 and 7% grades and one 8%. My diesel got 10.4-10.7 mpg and my gas truck gets 8.2-8.6. Again, same everything. And my Duramax absolutely sucked DEF when it was towing. Hardly used it empty though.
10k upfront for more power and more maintenance…. I’ll pass.
You get the $10k back on trade in. Longer oil change intervals and the maintenance really isn't that much more than a gasser. The costs come out pretty close, but you get more than double the torque
@@oldnumber6If your not towing heavy or up steep grades theirs no reason to own a diesel period. Also trade in doesn’t matter if it’s a diesel or not the market is what declares the trade in price.
Convenience factor is the issue for me. Making sure I get proper regens, long warmup in the winter, potential emissions system issues. Unless you're towing all the time, there's no point. Gas engines get it done and are better for everything else, especially with diesel prices where they're at right now.
@@SliderFury1Exactly people fail to realize DEF is another maintenance item fuel filter usually there 2 of them that get replaced every other oil change more oil required and the oil filter’s are more expensive everything about a diesel is more expensive and people fail to realize it.
@@Back_door_bandit_98well, most of them will tell you it's a little more but if you keep a diesel for more than 4 or 5 years (which really you should because one of the positives of the diesel is supposed to be its longevity) then you're definitely spending way more on maintenance over that stretch and beyond.
Diesel is king it’s undeniable get over it the gas motors are fine if you can’t afford the diesel
Love your videos. 8.0 mph vs 8.7 may not sound like much. But in a 1500 mile trip that’s around 25 gals difference.
I think it’s 15 gallon difference which is around 60$ extra if you got 8 mpg vs 8.7 mpg
But u got to remember diesels take def fuild also so really the diesel get worst fuel mileage
@@bigmurph1447def is cheap and you get about 900 mpgs for a gallon of def. Really a non issue.
@@shanebrown2963 oh its and issue waite till the system fails. All of these new diesels are junk because of the def system. Trust me I work on the junk all day long
Let's tow at Max payload for 300k and see where we stand? The gasser won't last that long towing nothing much less at max capacity.
But the average person is not going to tow 300k miles. Of course diesel engines last longer but they cost a lot more (initial plus maintenance).
Yeah no one keeps vehicles that long anymore. All the tech and junk will fall apart before the engine does (in both gas and diesel) so either get minimal tech or trade every 3-6 years.
And how many DPFs, DEF tanks, EGR, SCR, check engine lights will the diesel have in 300k? I would be much more confident with a gasser out of warranty than a diesel any day. A new gas motor is less than just a fuel system in a diesel. I have seen hundreds of gassers go 300k+ and never had one issue
That’s just simply not true. I work in the rail industry and all of our “small” trucks are 3/4 or 1 ton gas SRW gas trucks and they all make it over 200k before any real engine problems. And a lot of times it’s closer to 300k.
By comparison our main “section truck” with a GVWR of about 60,000 or 66,000 pounds (can’t remember right off) has a Cummins engine. It’s a 2019 model truck with 82,000 miles and it has twice stranded us for DEF issues. DEF tank level sensor and DEF quality sensor. Both times the truck derated and would not go 5 mph and had to be towed (this is a big truck too mind you, over 30’ long) to a dealer where we were without it for a week in both cases.
So let’s not act like diesels are going to go 300k miles when being worked. I’m not a diesel hater and they are far superior for hauling and towing heavy but with the government mandated emissions garbage they are woefully unreliable.
Okay I can see you guys really don't know what you're talkin about put them trucks side-by-side and see how big of a difference 2 seconds are when towing getting on the on-ramp it would make a big difference as well lol and you guys are running flat ground put them trucks on a grade preferably 15% and listen how you gasoline truck screams and run through gas shit I can take a Tacoma and Tow 10,000 lb on a flat ground and criticize the better truck for being 2 seconds fastest LOL I don't know if you know but that's about six to seven car lengths not to back the gas trucks too bad they have a time and place though I have gas trucks and diesel trucks and when it's time for real work I jump in a diesel oh and I almost forgot and you brought this up gas trucks do run higher RPMs but at the same time if you're going to work this truck you will want it to last a long time gasoline engines have a lifespan up 252 300,000 miles will be greatly reduce if you're at higher RPMs all the time Towing it will be luckily to get 150,000 out of a gasoline engine that is Towing all the time and this is why diesel trucks are better they running low RPMs therefore the engine last longer because they not working as hard but still has enough torque to get the job done and that little remark that you said if we were at sea level that gasoline truck will perform better well that goes both ways if that diesel truck was at sea level the turbos would have thicker air to compress which will mean it will get better fuel economy and horsepower as well
I would agree with you about the 2 seconds if it were an actual drag race but in normal driving that’s nothing. If you’re cutting it that close while merging traffic then you need to yield to the flow of traffic and wait for a better opening lol.
Also the diesel would perform better at sea level too but the NA engine is going to perform a lot better at sea level than at nearly 5,000’. The turbo is compensating for the less air density as compared to the NA motor.
Longevity is a non issue now. There’s no modern diesel that’s going to run for 200,000-250,000 miles without major emissions problems (probably would happen twice in that amount of miles). The gas trucks will make it to 200,000 just fine. The government has ruined the diesels. You can delete them but that’s getting harder to do with the EPA really cracking down on that. And the L5P it’s self is very expensive to delete because you have to buy a slave computer for it since the factory ecms are locked. I’ve heard prices as much as $8,000 to delete.
Both trucks have their place and both will do what 90% of the guys using them for need them to do. 7% grade is the max allowable on an Interstate highway. I know US highways and state roads will vary but wow, a 15% grade on a highway? 10% is the most I’ve ever seen and it was on a 2 lane that had a passing lane over the mountain. I don’t think that big rigs could even pull a 15% at any reasonable speed. Around here they can only do about 25 mph on 6 and 7% grades.
@@matthewanderson9912bro said 15% 😅
@@SliderFury1 yeah that’s crazy lol. Off road or mining/gas/construction roads sure but on a highway I don’t know lol.
I’ve seen on mining roads and road construction roads some pretty steep grades where they have to drag big rigs and concrete trucks and delivery trucks to the top of the hill with bull dozers but something like that wouldn’t fly on an actually public road lol.
Let us know where there is a 15% grade on a highway 😂
I have driven a 1995 Ford Ranger 2.3L 4 cyl 4 sp auto, towing 1,000 lbs over half a dozen grades of 10-15% during a 3-4 hour round trip. I could only grind up the mountain grade in 1st gear at 25-30 mph.
