I drive a Ford Bronco, and keep my BoB & a few misc items in a Rubbermaid container in the cargo area. I now it strapped down using folding eyes screwed into the walls and floor (you can get these at any auto parts store). Before that I just put traction tape on the bottom of the container. Kept it from sliding around, but it doesn't stop it from being launched at your noggin if you wreck
