Hey, this is my entry for the shuttle/refueler. It is about 35 tons, 80 -ish parts. It is fully equipped to do about 2 trips up and down from low munar orbit however it will gets stranded quite easily. It has no action groups. It has enough RCS ports to tip itself over to dock with the mun base and get back up. It is mainly designed as a shuttle not a tanker but it can do an alright job . It has a crew capacity of 8, 6 Jr ports and 1 regular docking port. Download: http://www./?12h4m74kzwha38f
