The LMM numbers are especially impressive considering the extra load from McD’s! 😂

I have a 08 gmc 2500 hd only has 107k on it I can say I take care of it and it’s almost same condition.maybe a couple of extra scrapes on the paint but I will say I have driven this all over and will easily take it cross country without a concern only thing I have done to it is leveling kit and 33’s on it they are so reliable .

Diesel foams a lot when filling, it can kick the pump off randomly towards the top. You definitely need to do more miles to get accurate readings.

LMM pre DEF! I have a 2008 2500HD with only 150,000 miles and does anything I ask. Will care for it until I bury it, will prolly outlast me.

I have an 08 LMM 3500hd 134k, Fass pump HSP all around Except egr is factory. PPE pans oil and trans 5/8 coolant lines w/Mishimoto transmission cooler, averaged 23 going to KC and back. Motor is completely stock I've got the 3" down not installed wanting to get a new turbo for even better boost and economy. I'm keeping my LMM till the day I die! No rust, interior is like that 09 constantly getting comments FYI, PULLS LIKE A BEAST.. 😊 And not spending money on DEF.

I dont have any of these trucks but I am really enjoying this comparison. Thanks guys.

Cool video and interesting for sure. Can’t wait to see the towing comparison. I’d pick an old truck every time myself. My 03 lb7 is not stock but I have less than $30k in it with having a trans rebuild with suncoast stage 5 parts and a triple disc tc. Same exact style start I do 5.2 0-60 with 33/12.50s. I have only pulled 12k load but it pulled it fine. Fuel mileage sucks though, 15ish empty but I don’t set cruise at 60 ever🤣🤣🤣

Great video

I have a Duraburb with an 08 LMM and Alison trans. It's a tank. Open road cruising it gets 20-22 MPG. I didn't hear it mentioned, but if there is a difference in the axle gear ratios, then the mpg and 0-60 isn't a fair comparison. Technically you would have to include the trans gear ratio, diff gear ratio, and tire diameters to make the comparison, but nobody going to change the tire sizes so they all have the exact same overall ratio. Still fun to watch.

I had guessed 8.5 0-60 on the 09 as well. I expected it to be competitive but not THAT competitive. I'm not surprised by the MPG though. That body style is actually quite efficient.

The banks derringer and pedal monster are well worth the money for the 23. In my opinion no 6 speed is going to tow like the 10 spd in the 20 plus. The problem with using so little fuel and trying to judge mileage is the amount of foam will shut the pump off at different times.. so unless you over fill it you're not gonna be very accurate

It's relative; using the same method on all 3 still give the nod to better fuel economy from the LMM.

I have a 2008 GMC Sierra 2500 LMM....and i love it!!!!....no issues...just a delete and stock tune....and its perfect. I got the exact same slt with tan interier😂

I love both trucks, check the GVWR and tow capacity of the 09 from the door stickers.

Are they all the same trim level? The trim levels have more sound deadening material as they get higher levels. My 13 Denali is super quiet compared to a lower level trim.

I had a 2016 LML and heard so many stories about the CP4 / snapping the crank so I got my 2017 L5P deleted / tuned gets 20 highway 17 city on a 120 tune

Rich that truck looks like the truck R3 took to sick week if so what a great friend . If not nice truck

I have 2 08 duramax they both are great they both tow my heavy 35 ft pj one has 420k mi on it and the other has 290k mi they both r tuned and deleted all the way no problem one is a 2500hd crew long and the other is a 3500hd dually crew long have more power than anything with the right tunes the heaviest I have hauled so far was 32,000 combined and on that trip I lost the trailer breaks but the truck handed it so good

I love my 18 L5P Denali.

I have a tuned LB7 with 270k and a 2020 L5P tuned with 60k. I'd have to say working daily I'd take the L5P, you can't beat the creature comforts. But I absolutely love both. The new one has some frikin snort tho but the ole LB7 rips too. I appreciate both in their own way. Both tow 15k lbs with ease and milage wise I'd give it to the L5P because of stock tires vs aftermarket on the lb7

Great content idea. I have an LML

I think the only benefit the LML and LMM have over the L5P is the true Allison 1000 trans. That 10 speed has a lot to prove if it’s going to stand up to its predecessor.

Depends on the setting the smallest distance average on the lml and L5p is over 25 miles and you guys only drove 21 so not the best test. Thanks for testing them.

07 LBZ Classic bought in 2011 as of today 318000 clicks on the ol’dometer heading for 1 million. Should take 27 more years to hit it. Wouldn’t have any other truck….till death do us part.

Lmm is probably tuned work at dealership and never seen those numbers on 09 and there a lot lighter

Throw some kryptonite products on the front end of that 09 and some fresh shocks and enjoy that 09! It'll tighten that front end up tremendously and the shocks, you would be surprised how much it improves the ride

I'm not a diesel guy but, even I know the "predef detuned" older stuff perform better. The EPA adds are the difference. We also know that the new trucks are capable of better performance but, only if you defeat all the EPA BS... I know you know this...😉

The 23 is definitely a better truck all the way around but it’s also medium duty capable which the 09 is just a pick up truck also the 23 is going to give you emission issues sooner than later I’ve seen more than a few in the shop for weeks because of the emission issues the 09 delete and enjoy being paid off.

Lmm needs compounds small fuel and a trans an send it

Are you all going to do collabs with R3? Not sure if ya'll still get along, that's not my business. Just wondering.

You can’t say it’s off because how do you know you stopped the pump at the same gallons that were in the tank as the last one …. Foam does trip the nozzle you can’t do that unless you had exact measurements of fuel sorry I don’t believe it mine says 400 to Emily and I’ll pull early 430 plus till I’m empty soooooo

23 L5p most definitely! Tune it and it will be stupid crazy

Sell the 23 and "build" the 09... eventually the motor tune exhaust wheels tires with airbags

Lmm’s are great trucks

Put a Banks pedal monster and derringer and that 23 will wake the f up. Lol

I still say get rid of the new one build the old one. A mild build so it's still reliable.

The 09 os alot lighter than the l5p if Im not mistaken

Sell the '23 and use part of the money for '09 upgrades.

Take 6 months of payments on that L5P and put it towards that LMM. Then you will have a beast.

I'd keep the 2023 unless you put a 1,000 WHP and 2,000 ft lbs of torque from a boosted 12 valve Cummins.

Dude knows nothing about cp3 cp4 or the hp4 injection pump

As sombody that's owned all of them....the l5p is the best out of the box. And with losing some parts....it's not even close.

LML is junk. Crank breaking, head gaskets, pistons crack, cp4. LMM is good because it’s identically mechanically to an LBZ. And the l5p is a monster. L5P>LMM and LML in the dumpster, LLY was the best! Until l5p came out,

That 09 is about 1,000 lbs lighter than the 15 and 23 and is for sure a lot more aerodynamic. I’ve had 2 06 models and they got better fuel mileage than my 14 lml.
