DEF in Ram
Would anyone know right off, what year the DEF Fluid was started in the diesel Ram's...was it 2011?

DEF is not a problem at all. There will always be those hesitant for change. Just add DEF about every 5,000 miles, a little more often if doing a lot of towing. For me that is about twice a year. Otherwise, I never think about it.
