Did you get anywhere with this? We are thinking of getting a Model Y and thinking about removing the 3rd row (and putting down a "finished" possibly carpeted surface) just to gain even more vertical clearance for our large dog to be able to sit up back there. We like the extra headroom the 3rd row yields for that row over the 2 row version. Curious why Tesla didn't give additional cargo space in the 2 row Model Y, and curious what's under that panel where the 3rd row seat bottoms would otherwise be?!?!
