I have a good friend whose wife drives a Yukon XL with that engine in it.

He told me recently they really like it. Great mileage and plenty of power.

That is the only person I know who has one.

I have a 2023 with 5500 miles and love it. I think it’s a different motor. Averaging 24 mpg.

I have a good friend that has one and has nothing but good things to say about it.

They revamped this motor in the 23’s for a reason !

Looking at getting one myself. Anybody have a good dealership they worked with around the Houston area?

I’ve got a 2020 and really like it. It’s got plenty of power, and drives really nice. I pull a trailer with it frequently, either utility trailer with a golf cart or a skiff. When I trailer the skiff to the coast I usually get over 21mpg. Without a trailer I frequently get over 28mpg. I will tell you that if you go much over 75 your mileage will suffer a bit. I have no complaints about this truck.

I'm following because I was looking at these also. I did read the 3.0L can't tow as much as the 5.3L gas. Kinda lost interest after that. The special Dexos oil & DEF are about to push me to the gas engine. I really want the small Duramax but I still can't convince myself.

How much do you need to tow?

How much do you need to tow?

As much as a half ton can. Trying to get out of the 3/4 ton business.

13,400 gas vs 9,300 diesel.

I had a 5.0 ford before my duramax, I never tow over 10,000 with my 1/2 tons. I also have ram dually for big hauls.

I have not seen anyone really complain about the towing power of the engine, but the rear end sags with a big load. Most who tow heavy add helper springs or airbags and heavy ply tires and are very happy. The 2023 with the max tow package comes with a 3.73 rear end and has about 13,000 pound tow rating.

Thanks. I did not know this about the 2023's.

I would absolutely despise towing 9K with a 5.3 much less 13,400. That’s a gutless engine if there ever was one.

[Keith]

Even though a max tow is rated for about 13,000 pounds, depending on how the truck is equipped, I wouldn't tow over about 9,000 to 10,000 after upgrading the suspension and tires. If you need to tow 13,000 just get a 3/4 ton.
