Sliding locking Truck bed tool box

Hi all,

Has anyone bought one of these? https://www.baaccessories.com

 

Seems crazy to me?

Before spending that kind of money on a box or system I would have to be able to comprehend in even a tiny way just how they work which I can not understand from the website at this time?!?!?!

Add to this that if I have a box at the front of the bed and want to be able to slide it towards the rear I cant have anything in its way at all which is exactly the problem with things in the bed already and not really a whole new way of organizing the bed which is what they claim on the website without demonstrating at all?

The boxes look nicely made I guess but they wont even show the price unless you add them to a cart which sort of tells me they also think the price might be crazy?

So I am always searching for something better but there is just enough info about these to sell me.
