I do buy my DEF at truck stops, at the pump. It's much easier with the fill under the hood of the GM trucks. But I do not by fuel at the same time, as the DEF fill is on the right side and I have to pull thru the lane the wrong way. Something I also don’t do with the trailer attached. All the pump DEF I’ve seen is either at a separate pump, of the DEF nozzle is behind a door. They are also much smaller as noted.
