It is pretty lame actually.. there are just large foam blocks where the headliner transitions to the cargo area.
Similar to this:
I suspect the blocks might also have a purpose in certain types of accidents....
I will be running a custom cut interweave wrapped piece of wood along the transition to make it look nice. I know some folks build a "storage area" above the driver and passenger but at this point I'm trying to avoid that as I like being able to stand up getting out of the front seats without hitting my head (and we pivot both front seats to face the rear).
