Grab a set of truck nuts while you're at it. It'll complete the ensemble.

That's interesting. I wonder why there's been no mention of this? GM was up front with the 87 requirement from the outset. Why build a big bruiser push rod for an HD application that recommends a higher grade fuel? For my money, I'd go with a F350 6.2/10-speed anyway.

Not ragging on your choice, either. The 6.6 is a nice upgrade over the 6.0's I'm used to driving and I'm still fine driving mine today. In the end, it needs to be reliable before winning a race.

The 10-speed is a must for the 6.6 to be performance competitive. I expect the Ram 6.4 8-speed to beat the 6.6, not as dominant as the 7.3, but the extra gears on the gas engines make them work better. It is what it is. The fact that the 7.3 is achieving 15mpg in real testing makes it the one to beat although it is an extra cost option. I'd like to see the F350 6.2 10-speed compared to the the 6.6. I bet it beats it. I don't tow 16K up the Ike but it's a pure torture test that exposes strength and weakness. I'm sure the added gears are not far off from GM but this was a sound thumping.

No worries there lol

At the price point and with the competition offering it it should be there. The adaptive part can be shut off and used as normal cruise. It's inexcusable not having it available on a $80K truck.

I got hooked on reading through this entire thread and the fact that the problem has carried over into some 2020's makes me thing twice about dropping money on one of these new gen trucks in a year or two. No matter how much they test this stuff still happens. Leaky window is never acceptable no matter the price point of a vehicle.

If they're able to add 1mpg to this truck with such noticeable size, power and capability increases they've done a phenomenal job in my book. The stats on the new 2500 make my 2016 look like a toy.

Just for reference, the K2's do have an issue with a rattle or click you experienced. There's a metal plate with 4 screws behind the hood latch and they have a tendency to come loose and cause a sound like you describe. It's easy to fix and lock tight solves it for good.

I've said it before but they're doing everything in their power to make sure to send their loyal customers to the competition for a good look. The heated rear seats and vents have been standard fare on the competition for years. Imagine paying almost $90K for a 2020 Denali HD and with no adjustable pedals. Who are the yes men approving this strategy?

They really should keep it as complimentary service. Nobody should have to mess around with an arbitrary point system to get the service, either. GM is their own worst enemy.

They're using the current but modified 6-speed for the 2020 6.6 gas but I think it's safe to assume it'll go 10-speed for 2021. The 10-speed makes gas engines much more attractive.

I get that it's a first model year but these trucks should not be let out of the factory like this. It really is inexcusable. Hard to enjoy your new truck when you have a major defect right out of the hole.

I bet the 2.7 will be no less long term reliable than the MDS V8's are.

Added payload doesn't explain why their main competition has a smaller and larger option. Small tank standard, large tank optional. It's not like having more fuel on board is a radical idea. This is GM simplifying the build process by limiting options. They're saving manufacturing costs and nothing more.
