I would pass on the disposal as well, one tank with big chunks is enough plus the greys DO NOT have rinsing capabilities to move them out. The galley grey water often smells worse than the black & can't imagine what it would be like with more food scraps brewing.
We had the dishwasher in our last 5er & from what I could figure used less water to wash a full load every other day or so than to wash a few dishes by hand 3 times daily.
