That's a nice truck Derek!
If I were looking to replace my 2500 HD I'd look at the 6.6 gasser. One of my friends just traded for his second and says the 10 Spd Allison trans is a game changer behind that engine.
I once chased him up Black Mountain on west bound NC I-40, I'm sure his gasser downshifted a couple but maintained 70-75 no problem.

Just this evening I had a discussion with a friend who is a dealership finance manager saying the same thing. My dealer has three C8's in stock.

Love my Denali Duramax!

I had a '00 Silverado that had about 216k on it when I sold it. The transmission was rebuilt at about 160k, the AC compressor at replaced at about 186k. To me that was pretty good.

I also had a '99 Yukon that was also a very good vehicle. I had to replace the the fuel sending unit in it and had a fuel injector go weak at about 185k.

I still have a '10 Escalade with about 79k on it and it has been great with no AFM issues, Only the folding mirror gear failure and as expected the Magnaride shock replacement.

I also have a '21 HD 2500 Duramax and so far so good with it.

I've never really bought a GM that was nothing but trouble. I find them to be reliable as long as you take care of them, use and work them but don't beat them to death.

Love the trailer. I've been pondering on either an enclosed or an open for my '68 Camaro to take somewhere every once in a while. I just find it hard to justify a high dollar enclosed trailer that may be only used once or twice every couple of years so am leaning towards and open trailer with a rock guard for more practical purposes.

My neighbor is the service-manager at the dealer I bought it from, so I discussed it quite a bit with him before I placed my order. The L8T 6.6L gas are the most trouble-free trucks they sell right now, since there's no turbos, no diesel emission systems, and no AFM lifter problems.

The 10-speed is fantastic. I hope I never have trouble with it after the warranty because I'm sure it's expensive as hell, but I sure am impressed with it so far.

Gas mileage is surprisingly good too when unloaded if you keep under 70mph. I got 17.5mpg driving it to Indianapolis for the 500 and 15.5 coming home into a strong head-wind. Another trip up North I got 18.3 on 60mph back-roads. It's tall and pushes a lot of air, so 75mph drops the mileage to about 13.5.

I'll take the 200k timing belt service over the almost guaranteed lifter failures that come with the 5.3L and 6.2L.

We bought a 2.7T for one of our fleet work trucks in 2022 because we couldn't find a 5.3 anywhere at the time. Before we pulled the trigger I told the Sup't who it was for to go and drive it and left the decision up to him (wait for a 5.3 or go with the 2.7T) because I didn't want to hear about it for the next 7-8 years if he didn't like it. So far so good. He says it actually feels more powerful on the low end than the 5.3.

Well,last night someone’s took my sons 22 2500 Duramax right out in front of his house!People suck,the guys out here have figured out how the steal the code from your fab and transfer it right in front of your house and drive them away!Thieves SUCK.Tom

Been going on for some time now, mostly used to steal Challengers. Once they capture the code and get in, they can reprogram the truck's computer to their fob and drive off with it.

Unfortunately, I doubt he'll ever see it again. That was a professional job with that level of sophistication.
