I saw this idea in one of the Bengelis books and then again on someones RV website. This is really a great idea. There is enough wood in the wing kit shipping crates to build two large storage drawers that can be rolled under the EAA style work benches. For my drawers, I ripped the pine sides down to about 7 inches and floored the box with the 3/8 inch plywood. I made it just long enough to slide under the bench and placed four 2" non-castering rollers in the corners. A couple pull handles on the front and you have a great roll-away storage drawer. All the material with the exception of the rollers, pull handles, and screws can be salvaged from the shipping crates.
