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.
well since we spend quite a bit of time in the winter in Idaho, MT, and occasionally the dakota's I've had plenty of experience with diesels and gas vehicles down to some pretty fridgid temps, Occasionally near -40F/C. And having previously lived in Montana for 25 years, I do have some knowledge about winter and vehicles.
