Which ‘21 Chebby 1500 Lt 4x4

[Bucknaked]

First off I’m getting out of the Super Duty trucks so I’m about to sell my 2016 F-350 King ranch SRW and down sizing to a 1/2 ton! It’s been a long time since I’ve owned a gasser ( other than my wife’s BusUrban). I’m a Ford man but I’m not paying the ridiculous prices they want for them so I’m making myself look at Chebbys ( I am not interested in any other manufacturers at all). So I need the Green Screens help. It looks like there are 4 gasser motors and 8 and 10 speed trannys. I know that the big 6.2 is a hoss but I know that they don’t pass many gas stations either! So please tell me about the other motors and about the Trannys - any problems with any of these items. This will also be a 4x4
And I’ll be pulling a 16’ utility trailer with a max load of 6k in the hill country
GO!

My old 17 LTZ 6.2 4x4 would avg 15-17 but on long trips 19-21.


It was the 8 speed. 10 speed is supposed to be better.
8 speed tranny is the reason I traded it in. Terrible transmission. Think it’s the reason they began putting the 10’s in the trucks as well. I may be wrong though.

Thanks! Same mileage as my wife’s BusUrban with the smaller 8! I thought I had seen some negative ion that 8 speed! Appreciate it

Ok so I know you are only interested in Chevys but I bought a 2021 GMC Sierra Texas Edition 4x4 5.3L engine this year and couldn’t be happier. Good mileage on the highway and I can pull my 20 foot trailer and 50 horse tractor with no problem at all. Don’t let those salesmen eat ya.

Get 10 speed transmission and the bigger Moyer 6.2 ! Just got rid of my last 1/2 ton truck all GMC all had transmission issues. 5.3 was dog !

Which ‘21 Chebby 1500 Lt 4x4

I’ve got a 2017 5.3 / 6 speed thats been a great truck and I’ve got about 170k on her. I can usually get 20+ mpg highway but I drive kinda slow. Tow my ranger regularly but that’s about it. Have towed a few boats in the past and hauled a 1979 Chevy k10 from Oklahoma down to Galveston. Never had any issues, but towing mpg isn’t good. Hope this helps.

Salesman- lol, they have ulcers after I get through with them

Well, I’m not against GMC either but they are all Gubment motors


Sounds good to me! Thanks

I have a '20 GMC with a 6.2L. I get the same mileage that I got in my '16 and '18 Chevy's with the smaller V8s, but the 6.2 has a lot more power. I'd probably get even better mileage if I'd keep it out of Sport mode.

My 2020 6.2 gets better gas mileage than my 2014 5.3 did

[Shane]

The old 6.0L gassers were the ones that got terrible gas mileage. I had one of those in a 2001 3/4 ton. It got 11mpg whether I was going downhill with a tailwind or pulling a trailer uphill.

My wife’s ‘16 BusUrban has the 5.3 and it has plenty of power ( I think we got a good one).

I’ll miss the 6.7 Torque and my 8’ bed for sure
But it’s just not needed anymore.

I’m leaning toward the 6.2

I recently got into a ‘21 Silverado company truck and have come to like it much better than expected. The 5.3 will move, and tows great if you aren’t trying to hold 80 mph.

I just got a 21 with the 3.0 duramax Monday. I’m liking it so far. Mileage is decent around town and short trips. Averaging 23 or so. However, it doesn’t take much of a trailer to kill the mileage. My empty trailer for my side by side with short tailgate knocked it down to 12-13 mpg empty. I traded out of a 19 2500 duramax. The ride is really nice. Smooth and quiet.

[Big Lee]

DO NOT OVERLOOK the 3.0 Diesel.

The 6.2 is a beast.

5.3 will handle your request.

I'd go 10spd for sure.

I say this from a highly educated point. Not a feeling. Highly educated meaning, I see these in action daily. See the repairs they need. Etc. PM me if you would like.

I have a 20 3.0 duramax 4x4 z71 texas edition and I am getting 25-26 going 80 on highway.
Pulled my trailer with mule and got 18.
Like it so far.
