Howdy y'all! Former Ram 1500 owner (which I loved!) looking into buying a new Silverado ZR2 with the 6.2. Love the truck overall (not a big fan of the Bose stereo. C'mon Chevy, do better!). Hoping to get some experienced thoughts on the truck and engine overall before I make a move. Thanks!
Absolutely love my 22 6.2!
It has had its issues, but not like Ford or Ram. All the main issues I've had have been electronic. (Radio, cameras) Got a new infotainment center and got it squared away.
Had a catalytic change already, but I think it was from putting octane booster that wasn't unleaded friendly in and it fried the sensors. (Didn't tell the dealership that though)
I only use VP Racing Madditive unleaded octane booster now and I use it every tank and haven't had an issue since. Definitely have to use premium fuel!! The 6.2 is a beast on power ( just stomped a Mustang Gt last night by 3 or 4 car lengths

)and milage varies as do driving styles. I've gotten low to mid 20's on long trips and average about 10 in the city.
A lot of complaints about the tire size, but I've had zero issues going where I've wanted. A few scrubs in the plates, but that's what they are there for. Anything above 35s then you have to worry about changing gearing and cutting to fit , ect ect. Bumper Mods are coming, but slower that I thought. I really want a winch setup, but got a Hi-lift jack with winch line, straps and a snatch block for a manual powered setup for the meanwhile.
I bought mine off TrueCar, so it was a no haggle purchase. If you go that route, you'll have to work with the TrueCar representative ONLY from the dealership you find. (Nationwide = Road trip

) Bought mine from a dealership in California about 300 miles from Vegas. All the other salesmen don't know anything about the TrueCar platform and will try and get their two cents worth and tell you some B.S. TrueCar sells for the price listed, not a penny more!
Change the break-in oil early, within the 1st 1k and every 2k after that. I use fully synthetic with fully synthetic Lucas oil stabilizer every change! Swear by it! Purrs like a lion, at 21k so far. Rotate the tires frequently, change out your filters and the 6.2 will treat you right!
The front locker has saved my butt more than once! It'll go where no RAM will

! Drives like a tank, all locked up in 4LO!
The multimatic suspension is fantastic, but you'll definitely feel the leaf springs without a load, but they are great for the extra weight of hauling and towing. Towing is a little spongy from what I've heard, but I don't tow much. I use a tow hitch storage rack and can feel the difference when loaded down for camping trips, but it's nothing to complain about IMHO. I also have an overland rack and a Decked system which adds a little weight as well, but it carries it very nice!
I bought mine for mixed use. Work, daily, camping , rock crawling and trails rides. Works for all scenarios!
I paid cash for mine so I'm in it for the long haul. I did about 6 to 8 months research before I purchased and in hind sight, I would definitely buy it again! Go drive one and that will help you decide. Like all the fellas here say, shop around to get a good deal! This forum has priceless amounts of info on the ZR2!
Hope you get what you like and welcome!
