Every since AEV first started showing concepts of their prospector/XL, I've been dreaming about getting one. The other day I was reading the recent "top 10 used overland vehicles" Here on Expedition Portal, and it said that the 2010-2012 Ram 2500/3500 was a top pick. Where I have a question is why just the 2010-2012? From what I can find, it was only minor changes from 2012 to 2013. I have seen a couple places that separate out the 2010-2012 from 2013-2018, and others that lump 2010-2018 all into one group. So can anyone explain to me what changed between 2012 & 2013 model years, and what would make the 2010-2012 more desirable than the later models?
