I have over 10,000 miles on my gas truck now. I average around 13 to 14 in town and 18 at 70 mph(I'm 56 years old). I pulled a 5000 lb sailboat from Texas to Georgia at 60 and 65 and got 13 miles per gallon. I purchased the 2500 over the 1500 because of price. Between the factory rebate and the credit union rebate the price came in at $10,000 less than the 1500. Something very noticeable is the difference in the power (and it sounds good). I average 5000 miles a year on the trucks I have owned. So the fuel economy doesn' really concern me.
A little stiff ride but it is a 2500 4x4. The interior is very comfortable and well built.
Remote start, bluetooth, plenty of power, and the heated seats.
Smoother shifting up and down during normal non towing usage.
