Just a observation here. The way everyone is making this topic sound, makes it sound like folks are going thru DEF like water thru a sive. A full tank of DEF should last you few thousand miles. If that's the case, then one should be able to stop at a major truck stop and get DEF (and fuel perhaps) right at pumps w/o trailer in tow or even in tow.
I will agree as well that I've had issues w/ the jug nozzle /vent location when I've gotten it/used it for my semi.......major PITA, but after re-doing the nozzle, was ok.
Usage varies wildly. Towing my 35k combined from WA to SoCal with DEF tank topped off at each end I used 347mpg.
