Congrats, nice looking truck. I got my 21 one year ago this July. It has run beautifully for that time, but they do take some getting used to depending on what you had before. I had a 2004 Ford F150. On the RAM I turned off the Auto Stop/Start and Hill Start Assist. I actually like the eTorque and its regenerative braking, but I also like manual transmissions. I can get the RAM to downshift three times on a long descent just by tapping the brakes. Averaging 15-16 mpg winter, 16-17 summer. Central Maryland, Appalachian trail area. Have fun!
