There is not a lot of difference, mainly the Y has a couch and recliner and the B has a longer "L" shaped couch and no recliner. Also, the wing of the kitchen / sink cabinet is stationary on the B and does not move with the full wall slide. The B, of course will have a DEF tank, where the 2010 Y may or may not, depending on the year of the engine. Either way I feel they're both a great rig....but then I'm prejudice...
