I think they changed the two 1/8" luan sheets glued together that formed the top layer for a single 1/4" Dynaspan top plywood layer. Otherwise, I haven't seen any significant change in floor construction. Of course I haven't seen "everything Keystone produces" so this is just a "personal experience".

There are some models that changed from the Lippert steel welded chassis to the ARCO "die stamped interlocking" chassis. But from what I've seen, the actual laminated floor is essentially unchanged except for the top layer.
