We keep two yellow plastic wheel chocks (which we rarely use), the original jack support tube, a 4 x 6 wood block, and the tongue-twister in there. Doesn't matter if they get a bit wet. The weep holes dry in out soon enough. We chock with BAL X chocks kept in the rear trunk. The yellow ones are for emergency use, or when we leave her at the repair shop.
