Plus the exuast, with the muffler opposite the gas tank in the middle. You can stick your head underneath the van, see what's where, and get a feel for where the floor is from the bottom. If you pull your rear seats, there are also some drain plugs you can pull out in some of the floor wells, and you'll see the ground straight through below. Basically, if you're asking "can I possibly modify this van to have more interior space?", sure. IIRC Skizo had a higher roof installed. If you need a utility cubby, maybe you can cut holes in the rear cargo floor and weld on a brace and a box that fits between all the stuff underneath. Move the exhaust. Ditch the spare. Do whatever you want. But if you're asking "is there a simple removable false floor covering extra interior space for comfort/cosmetic reasons, like in Gen-2", then the answer is no.
