I don't know about each model but as far as the Craz goes gator step flooring is now standard, fixed wakeboard racks are standard, the strainer and the 7 round trailer plug is standard, the windshield has a new design ( i don't think it is major but some kind of change), the surf flow 2 is standard. I'm guessing these are all standard across the board on all models but i know for sure on the Craz.
