"I have a 2004 Dodge Diesel that has 200,000 miles."
I bought a new 2005 Dodge with the Cummins engines and the NV5600 6 speed in late Dec. 2005. I wanted the NV5600 6 speed because Dodge was going to the Mercedes 6 speed in 2005. I had to search a lot of dealer inventories before I found a new Dodge with the NV5600 in Hudson, Wisconsin. I flew up there and drove it home to Texas. I love this truck but I wish I would have searched for low mileage 2004 instead. The 2004 didn't have a catalytic convertor and had less electronics.
