2005 with the 5.9 Cummins and G56 6 speed manual with a bully dog programmer. Everything works as it should. The rear end and transfer case were flushed and checked a couple years ago. the radiator was replaced within the last 6 months. It does have rust in a few spots. 213,000 miles and it does have a fifth wheel ball in the bed. Pickup runs great, Im just trying to upgrade. Seven eight five-eight one zero-8237 for questions.
