A brief description of the component in question would be appreciated. One of the benefits of describing what a rocker panel is in your own words, or even quoting and providing a reference, is that it encourages discussions here. From what I've been reading this morning the rocker panel is the structural and component of the vehicle immediately under the side doors, and also includes the visible panel. Is that a good enough approximation? If you're able to provide more information that'd be great!
