Jeff - it does say that, but its a general bed to fit all splits/bays/T25s
I'm quite confident that splits and bays have higher engine areas.
Can also tell from the picture, the mounting bracket that fits on the corner of the engine bay are about 3-4 inches below the surface of the bed... (which means the rear part would need to be raised to suit)
Have a look at the Volkswares beds on ebay, same mounting points/height etc, and says rear of van needs to be raised when fitting to T25
Sands - Not too sure about high level shelves etc, possibly some self tappers into the vehicle body, but probably wouldn't put too much weight on it lol
E D I T: just emailed rustylee to confirm
