EGR is barely used on the DEF era engines. The 14 and newer have been a phenomenal package. Great mpg, more tolerant of short trip/light duty drive cycles, extended oil life, two fuel filters which is something I feel should have been in place since 03. You’ll love towing with it. I’ve towed with my friends 15 and it’s unbelievable how it holds speed going down steep grades. I could practically take a nap compared to wheeling my 01.
