603Denali

This might be a dumb question, does the refresh have any ambient lighting inside? My 2020 has a couple small lights inside the door lever area, just curious if they added anything significant for the new ones?

My personal experience with the 6.2 and different octanes. When I first took ownership(2020), I was not consistent with using a minimum of 91 octane. Unknowingly at the time I was having a really rough idle and some intermittent engine/drivetrain shaking around 200 miles TOTAL on the truck. My truck was at the dealership countless times to diagnose the issue and they basically had no solution for me. I was angry and hated the truck, I even tried to get out of it and the dealership wouldn't take it back. I forget why but I started filling my tank with 91/93 octane consistently every single time and have ever since. All of my issues completely went away and I fell back in love. I am sure the truck adjusted the timing for the lack of octane, but it was extremely noticeable in my case. Hope this helps anyone on the fence!

I have an Ultimate held through GMC at my local dealership and my main draw back with the truck is Supercruise. I don't want it but it's standard with the package. I still have time to decide. My other gripes are Carbon Pro Bed(cool but I don't need it), Vader Chrome Grill(love it but why doesn't the lower grill match it), and no Panoramic sunroof...like wtf? I am searching for a Limited F150 to check out as well. RAM limited is amazing but I cant bring myself to buy a RAM.

I have the same issue. The temps have fallen dramatically where I live and this is the only time of year I have this issue. The first 2-3 times I brake in the morning I get squeaking, after that its gone. Come summer time, the issue is nearly gone with some occasional intermittent squeaks. Very odd.

If your looking for a dedicated snow tire with OEM specs, I run the Toyo G3 Ice on OEM High Country wheels(powdercoated black). For whatever reason it wont let me rotate the image and it infuriating.

Agreed, I have an Ultimate now but 80k? I know a Raptor is a different beast but I might be looking. None the less, impressive features.

4wd does a great job stopping, said nobody ever.

If you want to retain the OEM 22" tire size, I run the Toyo Observe G3 Ice. Never had a problem and they match OEM size perfectly. Great price too.

No stumbling at idle. Mine has shifting issues as well.

I too have the same problem with a 2020 Denali w/6.2. To add to this, if I am sitting somewhere at idle for more then a minute or so, I get intermittent stumbling. I run 93 octane so it shouldn't be the gas.

Any update?

A "reverse flow turbo"....mmmmmm k. Twin Scroll ring a bell?

Anyone install the GMC version and notice the passenger side being out of square with the truck? My drivers side is nice and parallel, my passenger side is EXTREMELY unparallel to the truck. I double checked installation, made sure the mirror was fully extended, I think I might have to exchange it! I know the pavement is uneven in the photo but trust me, its bad.

I have the rev x2, the finish on the side rails is peeling at the ends, the felt on the bottom has fallen off, the cover freezes to the side rails every winter. This is the LAST time I spend $900 on a cover. Also rattles when you drive so I keep my rear window closed. I will just go for something cheaper next time.
