Oh will be towing. 6/7
ha. My wife laughed. I’m not very “spirited” behind the wheel.

Absolutely zero DATA to support this... With EGR post DPF, and DPF close to Turbo to keep it hot and clean, probably one of the better designed light truck Diesels out there.
and I also have had 4 others besides this one. Worst was the Eco Diesel and was still covered under the emissions warranty when I had a problem. Many LM2's are +150K miles now and still humming right along. Are you expecting it to be a Kenworth?
Then 3.0 will work better gas mileage wise.

Look's like a lot of "zero DATA" below (especially considering this was literally 30 seconds worth of google-ing)

23' 3.0 Duramax emissions issues
Hi Team, I just bought a 23' 3.0 Duramax Silverado LT Z71 this past October. I have had frequent issues and had the truck in the shop going on 3x inside of 1500 miles for "Service Emissions System". I ran the trouble code and it came back with P2B97: Exhaust pressure control valve A position exce...

3.0 Diesel Emission Issue
I have had my new AT4 with the 3.0 diesel for less than a week. Put 500 miles on the truck mainly on the highway bringing back home from the dealership. My wife drive the truck home and stunk up the whole garage with a hot smell. Pulled the truck out of the garage and got an emission error code t...

You know, this very forum has a section just for the diesels, lets take a look in there on the first page and see what we find.
Yeap, emissions crap issues.
2023 Yukon lost power and P1098 code
I didn't see this code mentioned anywhere in forums for the 3.0L. We have around 55k miles on it now and before today we have loved the engine. Wife was driving and the CEL came on and lost power. When I took it to the dealer I noticed the cooling fan was running 100% and they said they have...

P1089 Code
I posted this is a Duramax forum and figured I would post here too..... My 2024 Suburban is throwing a code P1089. Its has less than 1500 miles on it. I took it to the dealership and they say it has gasoline in the diesel. I don't believe gas in diesel fuel is the issue. (It runs great) I...

DEF "contaminated"?
Tahoe threw a code yesterday when heading out with 1 segment of the DEF level gauge highlighted (1/8 tank?) and got a DEF contaminated (can't remember if that was the exact word) error and an admonition we'd be held to 65 MPH in 100 miles. Well, I stopped at the one Costco in the area without...

DEF level sensor issue
My 2023 Tahoe DEF level dropped the other day from 1/2 tank to 0 bars on my gauge and a warning of low level on the DIC, I filled the tank and it took 2 gallons so it was reading correct before it died but still reading 0. I have read of issues with the 21 and 22 Silverado needing a new DEF tank...

But there's "zero DATA" after all, so I must be imagining stuff.
All modern diesels (even the Kenworth's you joked about) are less reliable now than they were just 10 years ago.
Easy example, I have three Cummins 12 valve powered vehicles , in one case I swapped the engine into a Ford truck when the engine had 330K miles on it, no issues, would drive that truck anywhere without concern of being left stranded because of the engine.
Okay, this is a GM forum, my now old 2003 gasser 2500 truck with a 6.0 LS (well technically an LQ4) that I bought new, it was at 300K miles when I sold it, no engine issues, (it had gone through one transmission though), and that truck got beat with heavy trailers at high speed through mountains.
So what's different such that these late 90's and early 2000's engines where so much more reliable,,, oh yeah, the emissions crap they're forced to have now,,, that (and I repeat), will fail , will cost a fortune to fix, and will reduce engine life among other things.
The LM2 (along with all other DPF/ EGR/ SCR diesels) are crimpled by their required emissions equipment.

Why would you not tow w/ the 6.2? It has 460 ft-bs of Torque...The Duramax for 2025 and beyond has 495, they are in the same neighborhood.
I tow w/ my 6.2L all the time, it is a happy and stress free experience.
