MPG 2017 3500s pulling 22,800

I don't put a pile of miles on my truck but the difference in fuel economy between the Ram and the Ford still amounts to $1000 per year. If I was buying a new truck now I would mentally be adding 8k to the price of the Ford before making my decision on which truck to buy.....If this mileage difference proves to be a good indication of fuel economy over a wide range of driving and towing conditions I think it would be enough to sway me over to Ram.
