that figure to me is far more respectable and can probably squeeze some other stuff in but yes much more realistic...dont be scared off by 6.5" requiring to mod your door holes....its a piece a cake for any novice to do and can be done with tin snips...no specialist tools need..they just make it simpler and easier ... and takes about 15mins a door.....same can be done with the rear shelf so the spacers arent required.
