Dodge Eco diesel opinions

I have been driving the Cummins since 1996. Either 4WD LWB 2500or 3500 LWB. In 1996 I got 16 MPG with 160 Horses and auto. My 2012 has 350 HP/Auto and gets 15-16 MPG no trailer. Both got the same with my trailer. I see it as all good. between the Exhaust Brake and Tow/Haul, it is the safest vehicle I have ever towed with, never has one been in the shop for warranty work. And they Don't depreciate like a gas truck. as far as the eco diesel, my son had that engine in the jeep. it ran good, but was high maintenance. Fiat should have gone through with the smaller Cummins Instead of letting it go to Nissan. That was a big mistake. But, Fiat was cheap, as they owned part of that eco engine already.DUMB!
