This truck is a 2004.5 with the LLY 6.6 Duramax turbo diesel and Allison transmission. It has high miles, just under 277k, but the truck is in very good condition for its age. New Fuel wheels with new Nitto tires. I just installed new Skyjacker shocks on front, upper ball joints, batteries, console lid, a CV shaft on the right side due to a torn boot, and an oil change all last week. It also has a full replacement Ranch Hand bumper, in-dash DVD player, power telescoping mirrors, K&N air filter, and turbo back 4" straight pipe. There is a hole in the bed from having a turnover ball from a previous owner, it is covered by a rubber bed liner. Clean title in hand. Message, call, or text at 785-2zero2-0463 with any questions, thanks.
