We have wide, shallow stackable plastic totes found at WM in the front section. Organized to purpose and use. Tools and spare parts in one, outside cooking items in another, etc. When we first got our FW we struggled as well, all this space but we didn't want to just start throwing stuff in there.
We are currently struggling with our 6' folding table that slides into the pass-through and then we stack chairs, etc on top of it. Many times we want the table out without the other stuff but the table is the last thing to come out. Just don't know what to do :(
