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

You're right, 2012 on the chassis cabs. Not sure what I was thinking - I researched this prior to buying mine to make sure I wasn't a guinea pig with the first year release. Ram had emission credits that allowed it to go without DEF longer the GM and Ford. All of them now have experience with these systems and it should just be refinements until the EPA kicks in tougher standards.
