I am thinking about doing that too. I found the vent in the trunk, but I don't want to prop it open for the simple fact that stops moisture from getting in the trunk of the car. And there is no way that is the cause of my rear bumper rattle. I may just live with it and adjust the rear trunk lid a bit.
