We bring our 3 Duramax Diesel trucks back for the tow portion of our test! We compare loaded fuel economy and 0-60 times between a 2009 LMM (292k miles), a 2015 LML (220k miles), and a 2023 L5P (38k miles.) All trucks are GMC Sierra 2500 HDs (SLT trim if you were curious)

Which truck would you take?!

[@POHLHAMMER]

Old.

[@Guesswho69650]

I'd take a Ford

[@t.l.robinson2162]

The '09.

[@GK-gr2mx]

Both

[@Jdub-gb7ny]

23

[@t.l.robinson2162]

Keep the '09. Sell the '23 and have some money in your pocket.

I got a 2010 duramax. You can't beat no def fluid without needing a delete.

[@smitedude]

My 07 5.9l Cummins has never left me wanting anything else. Anything with emissions is a no go.

[@theglitch99]

Bought an 04 Ram 2500 w/5.9 and so far I'm happy!

[@nayo2897]

@@theglitch99are you still happy with it?

[@bartlettff]

Keep the 09 for a everyday driver and the 23 for hauling and trips

[@tmonster2247]

I have a 2006 2500 with 317,000 miles , triple disc tq converter ,EFI Live tunes and some supporting mods….I tow 20,000 lbs all day long….the body, cab corners and rockers are rotting to shit here in NY, but super reliable

[@bradenconway9066]

I pull 23k pounds with my 09 lmm quite often, pulls just fine. Only thing is the rad can’t quite keep up in hot weather but in normal weather it has no issues

[@bradenconway9066]

Mine is deleted and tuned as well. I run modified stock 95% of the time though. Even for towing, stage 5 is fun though, totally different truck with an extra 100 or so hp

[@seththompson9804]

LMM’s are known for their reliability especially when deleted. It’s just an LBZ with more emissions on it. As an owner of one myself I’d gladly take the ‘09.

[@berkeleyclubbeveragesinc.8445]

I have a 2010 lmm it's been a very good truck

[@DocGTO]

Ive owned 4 Duramax. 2009, 2014, 2016, and my current 2021. My 2021 out tows anything Ive owned in every way EXCEPT fuel mileage. My 2016 was deleted and tuned and was the MPG winner out of them all.

[@theglitch99]

No payment is a great feeling!

[@Travcity1]

Keep the 23. It will hold the value when you do go to sell it so it will not end up costing you as much as you think.

[@donaldsteere645]

I have an 08 duramax z71 I can tell you how impressed I am with it I have been offered 20k for it cash and it’s bone stock only Thing I have done is maintenance and recalls it has just over 100k light miles on it . Wish i could share a pic .

[@grantgauvreau2744]

You interested in selling? Located in FL

[@user-mr5rg1dg4i]

Keep the 23...love mine. Especially after it lost some parts in a lake.

[@theglitch99]

Lost parts😉is a must!😂

[@3_Klos1122]

The eagle has landed. Bring it home to roost.

[@melvinrawlings1457]

Keep the 09 fuck that payment😂😂😂. Keep up the great content. Much love from Maryland❤❤❤.

[@joeytaylor2785]

Yeah idk man. I have a 2012 LML with the tow tune, and I'm getting 13 mpg pulling a 40ft camper. The GVW of the camper is 11,500 lbs and its a bumper pull

[@rhb47150]

In my opinion you should hook up the gooseneck trailer and do a test between the 09 and the 23 to make sure it's going to be a big difference

[@kevinryan3241]

This is awesome content like seeing the comparison between the newer trucks and the little older truck I have a 2010 LMM and it suits me just fine and if you put a little power to that thing it’ll run right with that l5p but what I have to say is you said it yourself the payment on the 23 isn’t cheap and you could use that money to put into awesome content for the channel nobody really cares about a 23 truck even though it does pull good I think the money spent on your content would be better for you and the channel 🤷 just a thought I like watching all your content either way keep up the good work

[@TonyGabriele46]

Keep it the 09 Gmc Sierra 2500 Z71 Duramax Turbo Diesel Truck Keep.The 2023 Gmc Sierra Truck use it for a backup Truck Rich Rules

[@zachariahohlman7046]

Build the 09. I just sold a 22 half ton to go to an 07 lbz. No payment is super nice

[@diesel7903]

The 2015 is definitely deleted. Which impacts the economy in a good way and its on after market wheels and is lifted which impacts economy in a bad way.

[@ednesbit2988]

One more piece of advice keep your 09 fellas eventually the smog filters ( def) will kill those newer trucks I've seen 2 now a ford and a Cummins completely blown from particulate buildup in the systems just saying I've been at this a long time I'm 67

[@yourfavoritewelder3162]

Get a 4th gen Cummins if you want fuel economy. I average 3 mpg more towing with my Cummins vs my duramax. The duramax has a little more speed to it being a v8

[@CBR600RR05]

It’s the wheels and tires that is hurting the fuel economy on the LML. makes a bigger difference than a lot of people think

[@mini_max8725]

Keep the lmm. Mechanically identical to an lbz with added 5 hp in the tune and a DPF. Proven platform with the 6 speed. Throw some compounds on it, a lift pump and a solid single Efi live tow tune. Will pull anything and act like nothings there

[@sleddheadxp800r]

Since they don’t have evap you should fill them all pretty much right to the cap

[@jeremylakenes6859]

You should hook up to 12ft wide sheds and pull at 60 mph

[@ednesbit2988]

Love my lmm it's 2008 I'm 67 it will keep up with any new truck my friend has a l5 p and my lmm can keep up with it all day in fact I get better gas mileage and can tow just as much seriously I almost went new untill I found this mint condition lmm Duramax I'm never going back it's basically a Lbz with a def filter love my Duramax in not surprised mine had 133,000 on it it's basically new the interior is like factory new just a beautiful truck great video guys brand new subscriber Duramax for me period

[@haydenroyer]

IDC what the comments say, don't leave yourself with just a 300k mile truck

[@Collin2012]

He’s still got the Badillac!

[@justinburton5137]

I mean it’ll probably outlast the newer ones lol got an 08 with 426k hard hard hard miles and hasn’t left on the road yet.

[@andrewmacpherson6233]

Miles don't mean shit if maintenance is kept up on

[@dougsmith747]

05 straight pipe LLY for life. 😅

[@Bigchief421]

@ 3:45 looks like a spare plug cap arcing or?

[@CBR600RR05]

I would keep the 23 if you just need a good reliable tow rig. By the time you’re done, modifying the 09 with the year and mileage the worth of the truck Will not hold compared to the 23. You probably won’t really save that much money in the long run.

[@jport62592]

Rich rulez, what’s the dimensions on that legend trailer? What’s the load capacity or er?

[@richrules]

I think it’s considered an 8.5x24. Payload is like 8300lbs

[@CameronLegend]

Love my L5P

[@Chase-bn9ju]

Keep the 23 that 09 will only save you money until it has a MAJOR problem it’s coming it’s got 300k on it

[@kevinryan3241]

Super interesting that all those trucks are only off by a few seconds which in real life I don’t think honestly even matters do you think the extra two seconds is worth paying the extra 70 grand 😂 that my opinion I think if you put a little power to that LMM you’re gonna be delightfully surprised 🤘😎🤘

[@ryanharris2601]

Buy a six speed Cummins and put twin turbos on it now that would be cool or keep the 09 duramax and put twin turbos on it.

[@NightshiftCustom]

its them big tires slowing ya down

[@UTVoverlander]

Keep the 23!!!!

[@drewsayle]

Honestly it’s up to you. However if you can afford it. Your silly to get rid of your 23

[@kristauftransportation7616]

Tow the trucks with battlac!

[@Tlloyd56]

Nothing wrong with my 2008 duramax 155k miles. A 23 ain’t much better.

[@RK-jc5ey]

Lmao why didn’t you do a recap of the results 17:15 instead of just telling us your not supposed with them

[@ConnorsLandscaping]

Keep the 09

[@andrewmacpherson6233]

Keep creme puff

[@dwrowley]

Keep the 09 and sell the 23

[@briansaiers3147]

the DEF and all the bullshit on these newer ones kill fuel mileage.they should get a helluva lot better than that

[@bartlettff]

Letssss Goooo

[@jimmy4x4socal44]

Creampie

[@MrBpritch100]

Anything made in the lastd decade is pure and utter garbage. Keep the 09, be smart. It's just a matter of time before that 23' starts having issues that only the deepest of pockets are able to keep on top of...warranty aside bcz let's be real, your rig will be down for months while you pay out of pocket for a rental LOL.

[@Joseph96752]

Lmm to 14 lml is unbeatable and your opinion doesn't matter btw!
