It will be interesting to see the towing MPG results. We are averaging 27.5 in mixed driving with our Touareg 3.0 diesel, but only 14.5 towing our 4,500 lb trailer. If the Ram is averaging 24 in mixed driving, I'm thinking 13-14 towing...
Common wisdom is that diesels are best for their high torque. This Ram would have 420 lb.ft per US-News. I foresee just buzzing my way up a mountain pass, even at altitudes in Colorado. Are the diesels exceptional for fuel economy when towing, also? The smaller displacement surely makes sense for fuel economy. An engine that sucks in a lot of air to serve all those cylinders is going to naturally consume more fuel just to hit a proper lean/rich ratio. A truck could get smaller displacement with Ford Ecoboost or Chevrolet V6 with "active fuel management", too.
