Ours will be two weeks old tomorrow and I've only got 410 miles on it. Living in north Georgia it's a bit hilly and the other day we took a ride up to Brasstown Bald, the highest point in the state (4,765 feet). We live at about 1,100 feet. The best I had seen on regular highway and 2 lane road was a 24.6 average but saw 27.4 after a stretch of flat 45 mph on the trip the other day but still averaged 25.6 for the day (nothing over 55 mph). I'm happy with the mileage although I don't see where those guys in Colorado and Montana are getting 30. I can understand Florida and maybe Texas. The 2014 V-6 we traded in averaged 14.3 over an 8,000 mile trip pulling a 3,500 lb travel trailer and the 2010 4.7L V-8 we had before that got 22.3 over a 9,000 mile trip in 2012 (non towing). I was hoping to see a bigger gap between the diesel and what I was accustomed to but I guess 2.5 mpg better is still significant (over the V-6 non towing). With 410 miles on the odometer, the fuel gauge just passed the half way mark so I'm pretty sure I'll get 700 miles out of the first tank. I have to be happy about that.
As for pricing, I had heard that diesel always cost more in the winter because much of it is used for the home heating oil market which keeps the demand artificially high. Come summer when gas goes back up (and you know it will) diesel might come down a bit hopefully.
I've always liked the way Rams rode and drove (this is my 4th) but I really like the low end torque of the diesel and the somewhat instant power it delivers (compared to the V-6 Pentastar anyway. We haven't towed our new FF 214 WSD yet as I wanted to get 500 miles on the truck first and also, I don't want to de-winterize the trailer until we get down to Florida next month
