New guy here...   Hoping to give my .02 in case someone is considering the 3.0. And it’s also for the guy who is believing all the negative BS reviews like I almost did.    Long post, so

When I was shopping in November, I had salesman tell me: -1500 diesel didn’t exist -it’s a duramax/Allison so it will last forever -It’s a 1500 but can pull like a 2500 with the diesel

Crew cab short box?

Ft Wayne, Indiana assembly builds some crew short box. I am pretty sure all the CarbonPro trucks are built at Ft Wayne because the carbon bed supplier is very close by. I don't think the engine choice has much to do with where the truck is built though.

Do you have the "diesel off road package"?  I wonder why your payload is 200lbs lower than mine.

The regular 6.5 box trucks has a lower payload rating compared to the short 5.3 box trucks, the off-road package may also add a few pounds over the Z71 but I seriously doubt it.

So we got our 2020 3.0 Crew cab/short box denali in December and only had the chance to put a couple thousand miles on it.  ‘This week we finally got to take it on our first big trip out west.  We are half way through the trip and going through SD and WY we avg’d about 75-80 mph. We have 4 people in the truck and bed has luggage and supplies and we are getting about 25mpg. I realize if we went 55mph that we’d probably get closer to epa numbers but I’m pretty happy with this result. Additionally before this trip, with around town driving, we were getting consistently getting 24-25. We took this same trip a few years back with our suburban and averaged about 18-19 mpg.

Overall truck is doing very well and no issues- Its a pleasure to drive and comfortable for all.

Anyone towing in the 7000-9000 lbs range care to comment?  Debating between this and a Diesel HD - tow about twice a month, with a few weeks of straight towing here and there.

Yes, i'm towing a 7x16 enclosed. 7000 lbs is very comfortable for this truck. Only on steeper grades will it drop from 10th to 9th with cruise set at 65-70. Good news is the tow/haul mode is very well tuned so it will hold 9th for duration of the hill and prevent gear hunting like the gassers tend to do. Furthermore, 10th and 9th are such a close gear ratio that you won't even notice it if you are looking for it. I can't speak for 9000+ towing but unless you regularly tow in very hilly terrain, there's ample low end torque, smooth, smart and quite transmission works with it flawlessly. 

PS - anyone not sold on 3.0 vs 5.3 gas, wait until you go down a steep hill in tow/haul mode and listen to the turbo spool as it's vanes close to create back pressure. Truck will automatically down shift and turbo works to slow the truck down saving your breaks. Might not mean much to you but it does to me:)

Very interesting thread after 28 pages. I've been lurking as I'm considering a new pick up come later this fall and leaning towards a 2021 Silverado 1500, and now considering the 3.0 Duramax engine. It would be my first diesel so I am as ignorant as they come in regards to diesel engines. For those who have experience, do you see an issue with me only driving it 5,000-6,000 per year....it's going to sit a lot and mostly get used on the weekends for hunting, fishing. camping and long highway trips to see family. Thoughts?

Anti Ignorant Rule #1.  Put diesel in it.  (Dont laugh, when you're trained to head to the pump, diesel isnt on you mind)

 

Mine is used for weekend hauls and very short trips occasionally during the week (otherwise I use my car).  So far, totally content. tow a boat 9000lbs and and enclosed trailer around 2500lbs.  

 

1500 miles and I still have not noticed a regen - although Im sure its happened. I guess that is a good thing.

      Another 6.2L engine failure!

      By MASONV88888888 · Posted

      My 2025 Silverado 1500 had to receive a brand-new engine (long block) under warranty last month at only around 16,500 miles. Before the replacement, the truck repeatedly displayed "Engine Oil Level Low" warnings, even though the Oil Life Monitor still showed around 50% remaining after about 6,000 miles since my last oil change. After seeing the warning several times, I checked the dipstick with the engine cold, and the oil level was completely normal. The next day, the message escalated to "Add Engine Oil." At first, I assumed it was just a faulty oil level sensor, so I brought the truck to the dealership. After inspecting the engine, they found internal cylinder wall scoring and ultimately replaced the entire long block under warranty. Before this happened, I was planning to install a 4-inch lift and suspension upgrade on my truck. After needing a new engine at just 16,500 miles, I honestly don't see the point anymore. I also contacted GM to ask whether my vehicle qualified for a buyback, but I was informed that it does not at this time. Anyway, this experience has left me with serious concerns about the long-term reliability of this engine. I sincerely hope NHTSA expands the current investigation or recall to include 2025 model and performs a thorough inspection of affected vehicles. My biggest concern is that these engines may fail shortly after the powertrain warranty expires. If GM truly stands behind this engine, then at the very least, please consider extending the powertrain warranty to 10 years for affected owners. That would go a long way toward restoring customer confidence.

      OCI, not when but why?

      By Grumpy Bear · Posted

      Without exception but then I'm the odd duck, right? I know what goes into that test, how it is calculated and thus how to beat it. But EPA values are often not beaten by the general public and the government has in past years adjusted the means and methods to come to those values to more closely approximate "Joe Average".    The only real trick to beating that EPA average is don't drive like "Joe Average".    It's the same method you used to profit from "Economic Migration" and in doing so beat the 'stats'. But you, like me, are not "Joe Average".     The thing you don't seem to grasp is this "Purchasing Power Index" isn't forward looking. It doesn't predict what it going to be but looks backward and states what it was. They are not telling us what the THINK, they are telling us what they MEASURED. Example:    Wife says "I'm going to lose 40 pounds by Christmas". May she does, maybe she doesn't but the doctors office who weighed her when she made that statement and again at Christmas only REPORTS what the RESULT was. You and I can banter about what was possible and what aunt Tilly did till the cows come home but the result is the result. Arguing otherwise is.....irrational. That's all I'm saying. This isn't about:      What you are calling a 'Statistic' is a RESULT not a CALCUATION and as a result the RULE. Like gravity as a rule, it can not be broken.

      Rattle in the rear!

      By MASONV88888888 · Posted

      Just wanted to say thank you for posting this. Years later, your thread is still helping Silverado owners.   I bought my 2025 Silverado 1500 in January 2025, and I've had what feels like the exact same rattle since day one. After reading your findings, I believe my truck has the same issue with the cable carrier contacting the rear sliding window. To be honest, I had pretty much given up on pursuing the issue. It wasn't until I recently drove another brand's pickup that I realized just how quiet their cabin was—and how noisy mine has been all along. On my truck, the rattle happens on almost any paved road, gets even worse on rougher pavement, and I can even hear it during braking and acceleration.   I actually referenced your thread when submitting my case to GM, hoping they'll recognize this as a recurring issue instead of treating it as an isolated incident. The reason I reached out to GM first is because my dealership told me they would need to keep the truck for at least two days just to diagnose the problem. I was concerned that even after two days, they still might not be able to identify the source of the rattle before giving the truck back to me. I had also asked a few dealerships about this issue during previous service visits, but none of them seemed to know what was causing it or had a solution. That's why I decided to contact GM directly first, hoping they might already have an official repair procedure or guidance for this issue.   I also hope GM eventually comes up with an official fix for this problem. I have a feeling there are many Silverado owners experiencing the same rattle, but most either choose to live with it or simply don't know what the cause is.   Really appreciate you taking the time to document your diagnosis. Your post is still making a difference years later.

      Do you have access to BP fuels? Some stations have Silver 91 E-0 priced the same as their 93 E-10.  There is a local Marathon with 90 alky free for $6 a gallon but I go down the road to BP for $5-ish. They also have a 100 E-0 but that stuff is $10 a pop.
