I'm building a Mercedes Sprinter Van Conversion using a DC Cargo Horizontal E-track System so when ordering those components I noticed this and another style Hanging Cargo Storage Organizer so ordered them both. A couple days later I received them and am so glad they both fit perfectly under and adjacent to my bed (see in pictures) I'm not sure exactly what we're going to store in them but I know from past experience traveling we will fill it up with stuff...lots of stuff! Also very happy with the construction. Heavy canvas and very good and robust stitching with the same spring loaded clip on's that the other E-track accessories come with so it's easy on and easy off too. It fits perfect at 36" bed mattress support height.
