I like these, Mark. I am about to pull out my painstakingly,hand-crafted, sleeping and storage platform that I made of 3/4 inch furniture grade plywood. It pains me to take them out, but I am putting the rear bench seat back in place, and was considering building a new wooden storage unit behind the rear seat (not replacing the jump seats just now). But, your storage units look very functional.
I plan to taking some accurate measurements for an estimate. These plastic units have the look of steel cases - but are likely much lighter - yes?
