Ok all, here is my answer to the cargo organization issue.
It weighs around 15 - 20 pounds empty. Manual R&D and construction time was right around 3 hours. I skipped the drawer idea as this configuration allows much more space in the lower quadrant to be utilized.
Total cost of materials - $85.00.
As far as durability, today I had a packaged 50" plasma television partially sitting on the lower portion of the system and the rest on the folded seats. The cargo system never even groaned.
Enjoy!
