Ram 6.4 mpg

Every report of fuel mileage brings out many of the same comments. Especially those regarding hand calculating and of course those about your particular truck brand. Your numbers certainly look good and one can be certain no other brand with similar gas power will do better. My 5.7 with cyl deactivation has given me some highway numbers that I might not have believed, but were confirmed with the calculator.
Good report and much appreciated.
