I took a better look last night and that doesn't look like a possibility so I'll cross that dumb idea off the list. I think i'm leaning toward making boxes for the spare tire area that will sit north of the spare tire, right behind the seat back. Figure I'll cut that styrofoam insert almost in half and use it as a template on how much area I can use for the box. The enclosure will then take it's place and assist in supporting that floor. I'm trying to challenge myself instead of just defaulting to the rectangular enclosure idea, it would be nice to have it hidden under that rear floor.
