Here's my only problem with that pump location, there is no room for weight. We run 550's beside the motor and there is no way they'd fit with those pumps there..Under the corners of the back seat, there's two small compartments(one on each side) that never seem to get used and they open up into the back storage... why not there?
Also, for the front sack, mine is mounted behind the kick-panel in front of the drivers feet.
It would be a sin to use up all that room that could be used for weight...
Besides, how could you trust a guy with a purple boat?
