2012 GMC Denali HD Duramax

I have a duramax for sale. It has 217k on it. There is a misfire in cylinder 1 and I was told it would be an expensive fix. Runs and drives but runs rough. I have put it on and off a trailer a couple times to get it home and to the mechanic and then to my house. Its a Denali package so has all the bells and whistles. Leather, heated and cooled seats, heated steering wheel, navigation, wood trim, power windows, sun/moon roof and on and on. No fifth wheel hitch in it. Truck is deleted and 5 switch on the fly tunes. 5 straight pipe exhaust. Aftermarket front bumper with lots of lights turns night time into day along with the aftermarket headlights and bulbs!!!! All lights are led from the headlights to the license plate lights to the interior lights. Full length step rails and aftermarket tail lights. Rubber bed mat with a tonneau cover and cargo box lights. After market 20 rims with oversized tires. Was getting 15-17mpg in town and 18-22 on the hwy. love the truck but dont have money to fix it so its time for it to go and me to move on. Feel free to message or call with any questions or for more pics I have more I can send if you want. Clean title and title in hand.
