Ok, I'm looking at creating a freighter/(commando)assault ship for a game I'm planning on running. I need help with cargo space. How much space and weight are needed for 6 swoop bikes, a tank (comparable in size to a tie mauler, tx 130, canderous-assault, etc), a "jeep"-type speeder (i'll be developing that, too... I haven't decided if it will be repulsorlift tech or not) with seating for 5 including a turret and driver, a couple of holding cells, and enough more room for a semi-trailer or 4? What "current" comparable ships are there?
