This truck has had two owners, am the second one, 've had it for only 3 months I bought it thinking an ext cab would work for my family but with a 70lb dog and two kids it isn't cutting it so I bought a 4 door. the previous owner put all the miles on pulling a small fishing boat that fit in the bed of the truck and that was the extent of its use, he previous owner was an older gentlemen and kept amazing care of the truck its in near perfect condition, ou can tell its not like every other duramax in the pictures but moreso when you see how well it was cared for, ll the way down to the owner put duct tape on the paint under the slide in bed liner to keep it from chaffing through the paint...not much to speak of for options inside, t does not have xm, t has power windows and power locks, ench seat, installed window tint on all the windows, also installed a Compustar two way communication remote starter with lock and unlock features. I also installed a set of BRAND NEW 2015 Denali 18" wheels with factory michelin tires that came off a customer of mines truck with no miles on them, t most there is 5K miles currently on the tires! I also installed a set of Roadmaster active suspension helper springs in the rear as my plan was to use the truck for long distance hauling of my car hauler... truck is mechanically sound needs nothing ready to hit the road. Will deliver if needed. delivery NOT included in final price....
