That is what I thought but wasn't certain. I am guessing that is what he was doing when he was standing at the door for a few minutes
The rear suspension is really soft on my used 2022. From what I saw, they’ve done some weird stuff and had additional top overloads on certain trucks. I haven’t really figured out what package it’s part of. My truck didn’t come up with an additional top overload. I ended up adding a road active suspension just to get my truck up 1” in the rear then at the front. My work trucks usually gross around 9500 pounds and at that weight the rear my truck was a little bit lower than the front according to the fenders, which I don’t think is quite accurate because I think they made the fenders an inch higher in the front than the rear on these. My 2015 and older trucks suspension was perfect for what I do.His rear leaf pack does not squat nearly as much as mine does though. His is a short bed 2500hd zr2. Mine is a long bed 2500hd high country. I wonder if gm upped the leaf rating some on the newer trucks.
I have 30k on the truck now. No issues and my mileage has gone back up to what it was in the beginning. It changed after its last software update. I will say that the ride has changed. I have a section of concrete freeway that the beaming has gotten a little bouncer. Still love the truck.Everyone I know that got a single wheel 3500 constantly complains about the harsh ride.
