Looking for Ideas on rear window storage

[jsbihn]

Hey all,
I have heard somethings before done to the back side window areas of the H2 in regards to storage. Of course since I never really am looking out them when I drive, to me, I figured I could use this space to put various gear.
So I am trying to figure out a way to put racks or hooks ot something in that area to hang stuff from.
I thought I saw someone who had some spring loaded items in the window that held various items. In fact I want to say that the items that were put in the windows werent even intended for that, possibly a household item uses or maybe something intended for the garage.
(of course, now I can find where I saw that at)

I am not looking to spends gobs of money, if anything I am trying to do this on the super cheap.
I am trying not to drill and reconstruct the back of my rig, just do a basic add in to help with space and organization.

Thanks
