yes, thank you. End up going LTZ with 5.3. Very happy so far after a week or so of ownership. Much different driving experience than my last 5.3 with 6 speed. Averaging 18.5-19 mpg going to and from work with one stretch of straight highway at 70 mpg for 22.1 once arriving to the office.

I did notice that a couple of times and didn’t think too much of it. Mine 8 when I drove it off the lot.

Just wanted to thank everyone for their thoughts, comments and input. I drove my new pickup home yesterday, which ended up being a 5.3. I was pleasantly surprised how well the 10 speed changes that engine from what I remembered of my 2012. Very smooth shifts on flat ground and it never really felt like it struggled going up some of the small mountain passes on my way back home. Always seem to be in the right gear.

thanks! It’s been weeks since I was torn on my engine selection and decided to “split the difference” if you will and going 5.3.

Exactly! The lead time of an engine replacement is what’s keeping me away from the 6.2.

100%. I take it with a grain of salt. Still haven’t pulled the trigger yet. Playing the games with dealers currently. With how much inventory they all still have, they’re willing to walk away from deals over a couple hundred bucks. Onward we go.

Very much the same reason I’ve shifted away from the 6.2 myself which is a shame.

Thank you! I am really excited. Been almost 10 years since my last new vehicle. Looking forward to the upgraded features of a 2025 vehicle.

I agree with your fuel selection on the 6.2, if I were to go with it I’d run it with 91 since that’s the highest we even have in CA. I own zero equipment to tow so I don’t have that factor in my engine choice. I’ve driven both and you can for sure tell the difference but I’d only be getting the 6.2 for bragging right and less downshifting going uphill, faster acceleration, etc.

Ya, I'm going buckets. Over the past few days really leaning towards the 5.3. It best suites my needs a vast majority of the time.

Thanks for the replies folks. Keep’em coming.

The 3.0 fuel mileage is absolutely unreal. Glad GM still has this as an offering in the half ton market.

Wow. Impressive. Thanks for sharing.

For sure.

We have very few #2 diesel stations left in the state from my research. It's all bio or renewable diesel. The owners manual states you can run up to B20 but it's recommended to use a condition or fuel additive with it.
