OK, thanks. Then supercab is what Mazda calls Cab Plus (owner's manual). Mine has the two seats folding up different directions. Or did, I took them out, need to make platform for dog, other guy did it fantastic, with storage under. I just haven't done it yet. I did fix the suicide doors which wouldn't open because cable grommets at door handles were shot, I replaced with nice aluminum ones, they work great now. I didn't realize you could get cab plus (Mazda), or supercab (Ford) without doors, that would seem really dumb. I find them the cat's meow for putting groceries, better than a trunk, or hatch, or 4-door, or any other thing. Mine has alloys and factory (or dealer) bedliner, probably some other options, but they didn't get power locks/windows which would have been awfully nice. I saved jump seats/bolts in case anyone ever wanted it back stock but for me they were just in the way. Taking them out gives a fair amount more room. Of course they you have to deal with the unfinished part of the floor/side panels but the platform covers those if it's 8" high. You can do it and still have full recline on the seats at full-back. The only other thing then is that taking off the jack mount leaves an ugly place, some people put a cargo net over it. It's kind of tricky if you want to replace it because of the shape. One option would be maybe to put a panel over it, you'd only lose a bit there, might work. I wonder if any of the models had a panel without the jack mount there? Then it could just be swapped out. Thanks for all add'l info. Sorry if I got a bit off topic there.
