I'd rather see mileage results for a 100~200 mile run on a normal stretch highway.

Thats what this test is .... not 100 miles but a 66 mile loop of regular highway driving. I actually would consider a Ram if I thought it would get better fuel economy than the Ford. I'm pretty sure the Ram can display the DPF level so it is very unlikely that the Ram did a burn but maybe? If the Ford will actually go 30% further on a gallon of fuel than the Ram I can't see anyone buying a Ram over a Ford. On the other hand I can't help being somewhat sceptical of these results.

This is my guess as well that the RAM did a DPF regeneration during the loop. I can tell right away when mine is doing a regen. Mileage drops quickly. Based on the mileage I get in my RAM towing a big sail I am pretty sure it did a regen. It takes about 1/2 hour or so to do a regen on the highway in my experience which would mean that it was regenerating for just a bit more than half the drive. Would skew the results badly.
