I have two pass tru storage bays, in the fwd pass tru I store my Mtn. bike and tools. The rear pass thru I store a table, ladder, fishing rods in pvc tubes, oars and other long stuff. Rear storage has an inflatable raft , life jackets and fishing tackle. 5 gal water containers go in slideout storage. Oil, transmission and other fluids oil pan rags etc in another. The storage bays are only made from roto molded thermoplastic so I would not add shelves to put too much weight in there. I will miss the basement storage when I down size.
