The $2600+ cost difference plus the need for premium fuel just doesn't make sense. I gladly pay for premium fuel for our Mercedes, it has high compression and the performance justifies it, The 6.2L in the truck does not. Both of my previous F150 Ecoboost trucks were quicker and more torquey. Bought the Denali for the GM drive, comfort, safety features and the lux aspect.

That list of 15 vehicles spanned 40 years +/- normally drive a vehicle about 85K. Kept one GMC to nearly 200K, traded another in at 5K. The only towing I do is a 3750# boat and trailer. Very little offroad these days, the only reason my Denali is 4WD is to navigate bad boat ramps. I have less long term faith in the newest vehicles than in the ones from the early 2000s. The cylinder deactivation that GM is using seems to be a weak spot, I also question Ford's timing chain tensioners on the Ecoboost and the 5.0. Internet forums are where folks come to look for answers to issues and complain, so the likelihood of encountering any of these issues is fairly remote. My odometer rolled over 11K yesterday and so far all is well. I plan on driving this Denali for many years as I am recently retired and my budget no longer allows me to swap vehicles on a whim.

I drove identical 6.2 and 5.3 4WD 1500 Denalis. Back to back, over the exact same route and could not see enough difference to justify the cost difference or the 6.2's need for premium fuel. Coming out of an F150, 3.5L Ecoboost they both were pretty pathetic on the bottom end. I ended up going with the 5.3L and have been pleasantly surprised at how capable it is. Had I had needed more towing/hauling capacity the smart move would have been to a 2500 series Duramax or F250 Powerstroke. Wanted to go faster? Hop into the wife's Mercedes Benz

Mine kicks in at 112, which incidentally is the speed rating of my tires.

I've had the truck since 2/14 and just turned 7000 miles today. Had a check engine light come on and stay on. Took it to dealership and they did a software update that fixed the issue. Had something to do with the anti lock brake module. Other than an occasional funky trans shift, the truck has been great. That being said, I'm coming out of two previous F150 Ecoboosts that were flawless, so this GMC has some pretty big shoe to fill. Over the years I've had 7 GM trucks and 8 Ford trucks, probably had slightly less issues from the Fords but not enough to make me favor one over the other.

Watching this topic. Don't want to lift my truck at all, It appears that the 2" drop shackles should level the truck.
