I need to a nice cargo ship to help establish a 2.1+ base and here's a nice cargo ship!
I love the outside detailing and texture you got going, and the interior has a nice cramped Star Wars vibe. Again, fantastic exterior detailing.
The only thing I'd suggest taking a look at is that your stabilisers systems has a -167 integrity rating, and you do have a decent amount of empty unused space to the port of your crew accommodations.
I bet you could reorganize the interior system layout and fix the integrity problem and squeeze in a little more engines, shields, or cargo space. :)
The empty space is mostly to keep power and weight to a minimum since jumpdrive power consumption depends on mass. Also, power 2.0 will likely be tweaked some when the weapons update release.
