I know what your feeling, I love the Mazda just cause it has a bed again, My Nissan has 2 feet in front of notch and 2 feet in back and thats it haha! Im a big fan of raised floors, My Nissan will end up being about 3 inches deep.
there is another post about this i put on there all the info i could remember i have only done like 4 mazdas in the last 6 weeks and a nissan witch is the same
In my single, I wont have use for the bed, AT ALL. Front section will be sub box and tank, middle is the notch, and the rear section will be for the gas tank, and 2 storage boxes for misc. things.
