Your mileage suffers because air density decreases as altitude increases, But your cylinder volume stays constant. This means you're able to draw less volume (fewer molecules of oxygen) into the cylinders, the effective compression drops and the ECU compensates by reducing the amount of fuel added (to keep the mix proper)therefore using less fuel and less energy at higher elevations.
That's not the way modern diesels work and especially the turbo charged ones. The normal fuel air mixture concepts in gas naturally asperated engines don't apply to modern turbo charged diesels.
For the OP I can't see a 2mpg delta, but some Fl. stations are selling B10 which IIRC will give you slighly less mpg, but that should equate to less than 1 mpg non towing.
