bummer about the truck Kevin! I think I would stay away from the T100 though. There is just no aftermarket for them! What about an 05 access cab? I think you should be able to find a decent deal on one, and it is quite a bit bigger. or at least an extended cab 95-04.
Or cut the back bulkhead out and extend it 16 inches like one of the expo guys did on his Ranger.
