And also if a fixed cargo barrier is fitted,such as Milford,sliding the middle row seat may not be helpful for rear room,depending on where the barrier is fitted.
We will have to wait and see what the aftermarket companies come up with.
FWIW,there was a pic on another site of a factory front bar,which is apparently available in Aus.Same as the one in one of the earlier spy pics.
Not a full bumper bar style as most of the bars are here.
