I think the storage space is exactly what you see - everything on the bed, and the small boot area at the front.
But the tyre is sitting on the ground in display mode, and doesn't look like it fit in the boot, which means rattling round in the main area.... ??
The comment about Outback was tongue in cheek - if they had an outback version it would take it over the ATM of 749kg, meaning brakes. thus defeating the purpose.
