I would be interested in the floor load floor for the Model S (part # 1005534). I noticed mine on my 2017 is made from pretty crappy material while several of my friends 2015s have a very rugged load floor made from hard plastic material instead of particle board (or whatever they are using now). They are the exact same size (I know I tried to swap them when their were not looking) but the older ones seems to be made much more rugged!
