Monster Box 30 Overview

Durable Owl Monster Box 30 van storage box mounted on vehicle at sunset

Massive Size, Minimal Weight

The Owl Monster 30 is the perfect secondary storage space for any gear that's better left outside the van. With 6.65 cubic feet of internal storage, it's ideal for recovery gear, tools, dirty shoes, and even misbehaving children. (Please do not put children inside the box.) All of this storage space comes in at less than 60 pounds because of our lightweight, TIG-welded aluminum.
