Quick dismount bed box

I would like to buy a bed box/tool box such as Weatherguard or the like. But I use my whole bed for hauling brush and slash several times a month and cannot sacrifice the space to mount one permanently. I haven't found a box that advertises this capability or mounting style when searching online. Have you faced this problem and if so how have you solved it?

Thanks

 

Bump.

 

I was thinking about that as well, I was thinking that I may be able to mount the box to the bed rails for easy removal. I haven’t had the time to research a box that fits yet, so keep us posted if you come up with a good solution,

Nice! I like that it is below the top of the bed so it doesn’t block the rear view.
