Typically engines built after January 1, 2010 had DEF. However, Newell buys engines in large batches so I have seen coaches as late as #1451, a 2012, listed as being No DEF engines but do not have personal confirmation on that being the case. #1421, a 2011, was listed as being a No DEF engine. The floor/elevation plan for #1462, a 2013 specifically lists a 15 gal Urea tank.
