I've tried folding mine when on weekends away as it hides the luggage in the back. Trouble is the tonneau is quite bulky and when folded or rolled up it fouls the seat belts where they come up from behind the seats, if you lean forward and pull out more belt it doesn't spool back when you sit back again :-(
I think the half Tonneau is the way to go if you want to cover only the rear compartment.
