2017 GMC/Chevy DEF tank!

I agree that the DEF tank could have been designed differently to look better and not hang down so low. I have it on my GMC. I will admit however, that I am very impressed with the emission systems technology and the effectiveness of these systems. The current generation Duramax is very clean and I think they have come a long way in controlling emissions. I have no smoke and absolutely no black residue in my tailpipe (look at any gas motor tailpipe and compare!).

These trucks have had clean tailpipes since the first DPF truck back in 2007. 10 years now...

Yes the technology works. I can put my face up to the tailpipe on my 2012 LML and it smells like the air coming out of a dryer vent. The downside to all of this is all the sensors that come along with making this technology work. One sensor goes bad and you can find yourself on the side of the road in limp mode.
