I saw the swing out box, it's really neat but not what i want. ?I think it will be awesome for some people but it doesn't fit my needs.
It's too much trouble to take stuff out of the box if you have the swingbox loaded and the space next to the box loaded. If that happens you have to unload all the crap on the right in the bed first to swing out the box. ?I like the bedslide idea, just like pulling out a drawer.
Now mounting one of your boxes directly to the bed slide might be a good idea.
-- or maybe the box can be modified so it can either swing out or slide straight back?
any way, I still think your idea and execution of it is awesome, you will sell a ton of them
