It's not a long-duration ship, is it? At most you'd have 4 crew, and then you'd have the troops being transported.
Then of course you don't rotate 3 shifts on a ship like this. At most your rotate 2.
In FFG's write-up, it has half the Consumables and roughly half the cargo capacity of the YT-1300. That could be because it's designed to hold more troops, but the write-up doesn't give it those.
