2022 GMC AT4 Limited for sale. Currently only 21165 miles on it, so still have just shy of 15,000 miles left on the 3 year/36000 mile factory warranty (or until November 2024) Factory 2" lift, sliding rear window, heated/cooled leather seats w/ AT4 trim, a ton of bells and whistles. 6.2L engine, 8 speed transmission, gets good gas mileage for the big motor. I absolutely love this truck, probably the best vehicle I've ever owned. No trades, and if the ad is still up, its still available.
