Just got home tonight after a 9 day road trip with my 2017 2500 Cummins. I didn't tow anything and the only load in the truck was me & the Mrs with our luggage and a cooler or two. The first leg started in Portland OR and continued through Boise ID, Provo UT, Flagstaff AZ and ended in Phoenix AZ. That leg started on 11/29 and we arrived in Phoenix on 12/2. After most of a week of running around in the Phoenix metro area with all those crazy drivers at high rates of speed, I put the wife on a plane Friday and I headed back to Portland via truck the next day. This time the route was from Phoenix to Apache Junction to Wickenburg AZ, on to Kingman, through Las Vegas, St. George UT, Salt Lake City, Boise and eventually I ended up back in Portland. I left Phoenix on 12/7. I can be a Road Warrior when needed. Both of those routes have some significant elevation changes and freeway speed limits ranging from 65 MPH to 80 MPH. I made best use of the Cummins power to cruise up and over those hills with ease and at the posted speed limits. I admit I rode it hard and put it away wet but the Ram didn't seem to care. My total fuel usage for the entire trip was 158.19 gallons. I traveled a total of 3370 miles and even though I had quite a bit of around town driving I still managed a respectable 21.3 miles per gallon. The truck ran flawlessly the entire trip.
