DEF isnt a terrible pain, to be honest. Its just another expense.
I dont have to fill the DEF tank every time, and about the 3rd fillup of my twin 150 gallon tanks is when I need to. Most fuel stops have bulk DEF at the fuel islands, I just pull out a different nozzle when I'm done fueling and press another button.
The return can be quite well if you know what you are doing. When I worked in Springfield, IL as an apartment maintenance guy, we had a rash of air conditioner coil thefts. So much so that on a lot of our buildings we had moved to roof mounted units. The guy stealing the copper knew exactly what to unbolt to slide that coil right out and run. We were not the only apartments to lose these, either. Even businesses were getting hit.
