Nothing pulls like a diesel (it’s in the physics – lol), but emissions equipment peripherals can trigger check engine lights, added maintenance, and potentially, even the dreaded limp mode (Ugg!), though I believe that DEF has taken some of the ‘heavy lifting’ off the under hood stuff (lessening EGR dependency) by chemically treating NOx within the exhaust tract. Still, more pollution devices require more servicing ($$) than a gasser… Depending on one’s situation, Fords new torquer 7.3 gasser offering might be a viable alternative, but when it comes to heavier campers, long grades and towing, only time and more reporting will tell…
