No DEF for 2020 Emissions??
Has anyone else heard any rumblings on DEF being eliminated for 2020 emissions? I've heard it from 2 different people, but have NOT seen a thing in any semi web site or on a trucking radio show.

They are eliminating the EGR valve on the Cummins engines in 2019 model year. All emmisions will be downstream in the exhaust, and DEF is going to be part of it.
