I wish my truck had the 6.2, but I didn't want the "options" that getting a 6.2 required for free, let alone the upcharge.
You're kinda "that guy" though. Everything I have is the best and that's why I have it kind of guy. Non stop CST is the undisputed king of lifts because I have CST. 6.2 is better than everything because I have a 6.2. When researching lifts your posts kept coming up... My suspension guy said CST is the best so nothing else compares. It gets old and trivial. It's hard to believe any of your posts are unbiased
5.3 will get better mileage, there is no argument there on stock trucks. Now modded with big tires, yeah, I bet the 6.2 handles them better. Doesn't lug as easy and will stay in 4 cylinder mode easier. Especially since you're probably running 91+ octane, it will have less kr if any with big tires on a stock truck.
