First drive Ram 1500 diesel

I want to add that efficiency seems to be extremely touchy with the Ecoboost. If mpg's are on my mind every minute and I get a little lucky not catching lights, I seem to be beating EPA estimates. However, if so much as a bird craps on my hood, the numbers plummet fast! For about a quarter tank I drove around having "fun", and the bottom fell out very quickly. Fortunately, my driving style will keep me on the better end. Wouldn't mind enjoying the power more though.
