I wanted something with a bit more mass, something that actually looks like it can hold fighters.
So, maybe a bit more 'bulky' feeling.
The Salvager doesn't really have that, it's just wide. It's too spindly, and it doesn't really have any place for fighters and similar sized craft to dock.
Slave liner is a good ship, my junker flies one. It is quite large, slow, and has a bit of firepower too (11 rear turrets, 10 forward turrets, though all transport and no cap weaponry). It also has something that looks like a docking bay on the underside at midship.
Maybe a bit too much, but try the Liberty Assault Carrier.
That is, if the Slave Liner doesn't work. Always gotta have a Plan B;)
EDIT: Haha, after all, it is bulky
