How could this be?
I usually get around 13 mpg when pulling my 33ft,11000lb loaded, fifth wheel. That, of course, is on flat ground doing 60 with no headwind. My truck is a 2018 Ram 2500, diesel with a 373 axle rating. ...

Diesel #1 could cause a small dip in mpg because of the increase cetane.
well, #1 has a lower energy content/gallon, that's more the cause of lower mileage, not the cetane rating. And about now is when "winter blend" diesel starts showing up at the pump which is either #2 with additives to lower the cloud point, or #2 and #1 blend, or a combo. But in any case expect a drop in energy/gallon with winter blend= lower mpg.
I had to bite my tongue for a while, somebody from the left coast trying to tell us about diesel fuel, lol.
