The problem with leaving the full tonneau on Peter and tucking down behind the seats is that it interferes with the seat belts. With very careful folding you might get away with it but I could never fathom it out! A pity as I like using the tonneau half done up when I drive the car without side screens. I've just picked up a mohair half tonneau from Allon White today which I prefer to a hood cover and it also nicely covers the luggage in the car without interfering with the seat belts.
