This is a fully loaded 1 ton extended cab dually with the LT package (leather, power everything, OnStar, premium sound, ect). It has an 8.1L gas engine and an Allison 5 speed transmission. It runs extremely well and will pass inspection and emissions without any trouble. Comes with heavy duty towing pkg and gooseneck hitch in bed. Has good tires, tinted windows and much more. I can send a full vehicle history report to anyone who would like to see the clean history; this truck has never been wrecked so I have nothing to hide. Call or e-mail with any questions. Thanks for looking
