the thing you should look at is what year the sprinter chassis is on each. there were several additions by MB to the sprinters around them most notably the luxury packages. since it's not uncommon for an rv year to be different from a chassis year you should look at that
a 2013 pleasure way could be 2012 or 2013 chassis.
a 2014 pleasure way could be 2013 or 2014 chassis.
lots of internal changes on sprinters in those years
