Campervanners often have to rummage. It can mean to search untidily and unsystematically. It doesn’t matter how tidily and systematically you pack your van, that kind of approach never works when it comes to finding the corkscrew and chocolate.

A rummage can be a confused miscellaneous collection. A rummager is someone who rummages. Once you’ve finished rummaging you will have rummaged for long enough.

To rummage out is to find amongst other things. To rummage about is to disarrange. (That’s another good word)

Rummage also refers to the arrangement of casks in the hold of a ship. That definitely needs to be done tidily and systematically or the ship will become unstable. Also it’ll mean the sailors have to rummage about to find their rum.
