I ordered a model Y and it will be delivered soon. I got the 7 seat configuration. I am curious if anyone knows if the rear-trunk liner works when the rear seats are down? I do not want to spend $130 on a liner that may not work with my configuration. The sale page and manual link are both pretty sparse on details and do not mention anything about the seating configuration. I mainly want a liner for the occasion I need to take my dog somewhere, in which case the back seats will be down.
