Ordered mine April 14th delivered May 14th with Cargo net. It is a well designed extra and well worth it.
As I remember it didn't show up as part of my build when I checked the online status but when dealer check there access it was there. That is the only issue I recall. It would be a lot of trouble to add-on because of the fixture on the back of the seats and the overhead fittings. Not sure a dealer could handle it. This is why I recommend getting it with your order. If they don't believe it is available just show them the AV manual offered demonstration on how it works.
