Patent may confirm two things:
-roof rack standard on all trims with hardtop
-hardtop is 7 piece modular, as leaked by insider months ago. Too much thought went into removing the panels to only have the rear cargo section in one giant awkward and hard to store piece
edit: crossbar most likely...
Other than Wrangler skytop or whatever the hell it’s called, no other vehicle would have that large of opening at the top. And with Skytop, you remove rear windows
But if the back can't be stored, then there's no point in the rest of panels being stored. You aren't going to drive around with the passenger panels off, and then keep the rear piece on - it would become a sailboat
