Go with the 6.7 or keep the 5.9?

The power and performance of the newer DEF trucks is awesome. The DEF is not the hassle you think it is. two or four jugs a year is all I go through depending how much towing I do.

I had a 98.5, then a 2001, and I did some mild bombing to both. They would make me proud every time I put them to work. I've had my '09 for a year, have deleted it and added a tuner, and I think it's a great truck. I spent several years learning all I could about 2nd gens, and I'm in the process of doing the same with this 3rd gen. TDR is a great resource.

I am on my 7th Dodge Cummins PU. I am also a diesel hot rod guy (been tractor pulling for years) SO 6 of those Cummins engines have been modified to tow better.. THE 7th (the 2013) has 46,000 towing miles on it and is BONE STOCK..... I am very happy with the new truck. The DEF that I feared so much has turned out to be a non issue for me.
