AnotherFireFox Aerodynamics presents you Autonomous Transport Vehicle, a reliable and efficient way for your orbital logistics. You can also use this craft to make an impromtu space station - it has docking port both side!
As real Orion MPVC and ATV do, this vehicle share the chasis to Eridanus MPCV of mine. However not carring heavy crew module, this thing have 2,000m/s dV. Still there are a lot fo free room, especially in front section, so no worry if you want to refuel your craft or station.
