I made a refueling platform that was launched into orbit empty. I then can send up my three (three so far) refueling modules, one for liquid, one for mono, and one for xenon. The modules can dock with the platform and transfer their fuel to the central tanks and stay until they are almost empty and then undock to deorbit themselves making room for more fuel. It has docking ports for 8 large refueling modules (the liquid and rcs stacks) and 4 more for smaller modules (like the xenon). Four spacecraft can also be simultaneously docked for refueling. The fuel lines are oriented to take fuel form the module docking ports to the center and distribute it to the ship docking ports. While this doesn't matter I wanted to make it a little more realistic in its design requirements.
