Finally got my 2014 and am posting pictures of the difference between the 2013 and 2014 top decks.
I stocked up on 2013 top decks and have the low traction ones too so for those who have 2013 spares lying around, the old one will work, its just that you won't be able to use the 2013 motor mount hole. Also, the 2014 does away with the first hole for the steering support on the top deck (there are 2).
