I initially thought the DEF deal was going to be a PITA but it's no biggie at all...and I can't smell the slightest hint of diesel fume in my '18 2500 GMC. One thing tho, it's heavy and will get you stuck deeper.My wife hates diesel too, however the little 3.0l Exo boost she couldn’t even tell it was a diesel. Those little diesels with DEF have come along way compared to their bigger brothers.
