I carry a modified expedition, and I tell my wife it is a "gear" bag. She too calls it a man purse. I carry lights, batteries, first aid kit, chemical lights, monocular, extra bulbs, pens, am/fm/sw radio, anti bacterial hand wash, sewing kit, sdu light, and all sorts of things I would want to have available if I should ever be in a situation such as the twin tower tragedy.
I mean after all I would rather have it, and not need it, then to need it, and not have it.
