My truck is a 2001 Dodge 3500 Dually 2wd with the NV5600. It's stock except for a 3.5" straight exhaust. This truck was a tow vehicle before I got it at a great price. I had a 1984 Ford F250 years ago with the 6.9. That's when I knew diesel was my engine of choice. Recently I had owned a Mitsubishi/Dodge D50 with the turbo diesel and would have kept it but had no place to store it at the time so it is scrap I'm sure by now. I'm totally addicted to diesel performance and hope to post all the things I do want to do to my truck. Thanks in advance for your experiences and advice. Mike
