I took this picture at the NYIAS. The fact that the 3rd row has gap skirts leads me to believe that they told fairly flat.No, because of range, I want to put it in the car.
I wander also if there is flat bottom, when you fold the seats of the second or third row. From one video I have seen I have the thinking, at the tailgate the bottom is lower than where thjie seats are folded (but no clear photo with folded seats and open tailgate).
