I have a very hi-tech solution, LJ. I use the space to stow 2 plastic boxes loaded to the gills, that just fit; to get the box out of the back... its pushed up against the back of the space... I have a 1x2 about 3 feet long with a hook in the end. I could share the plan for making this stick, but the patent is pending... you understand?? I also store chairs aft of the boxes in that space, but can reach them from the outside... or might go hi-tech to get them out as well.
I thought about making a pull out shelf, but you can't get as much stuff in there that way.
