The frunk. When I NEED to STORE the humps... they go in the frunk. I don't cart them around when I don;t plan on using them, and the frunk is not the long-term solution to my storage needs... for the humps lie 'flat', in their bags, and under my bed until used. If they need to come off the car for one reason or another... in the frunk they go. Much cooler than the oven trunk.
