With the plywood centered between the wheelwells there is about 2-3" gap to each wheelwell. If I move the plywood over so it butts up against the plastic door sill molding of the side doors that makes about a 1" gap to the right wheelwell and maybe 4-4.5" to the left. There is still about a 1.5-2" clearance to the right door frame with the offset. My thought is to put it offset and have a little larger "me" space along the driver side wall for my stuff. Any van drivers with an offset floor and if so comments please.
