First I was thinking about using Rubbermaid totes for everything, cheap enough idea. Then I realize how often I hear about how people get ripped off. So I started looking for best ways to haul hunting gear found out about lock boxes seemed like the best way to keep thieves away. And like the idea of having them bolt to the box all I need is to keep them out of the weather I bring other items that are above the bed so a fiber glass topper was what I was going to do. But taking that off every summer would be a process. What about canvas tops ?
