2022 GMC Sierra SLT 4x4 with the 3.0 DURAMAX. Truck is in excellent shape. Averages 24 mpg with the best at 29.5 mpg. Truck has been maintained as recommended. Transmission fluid and 4x4 transfer case were serviced at 75k. The only reason I am selling is I purchased a new one. Please reach out with any questions.
