Bought my 2500 new on the fall of '96 and have never sat in or driven another Dodge/Cummins since. Almost 400k on the clock right now, and am thinking about a new one this fall. I found out a lot by just reading the manual. Do a Google search for "2014 Ram owner's manual" and then look for the "Diesel Supplement". It will be a quick PDF download. Lots of updates in there for me. I'm going to have a lot of homework to do it looks like.
