Hey folks, first post here. And i would like to introduce my first _successful_ heavy tanker: [Game Version 0.19.1, MechJeb 2.0.7] It delivers a complete Jumbo Tank and a lot of Monopropellant Fuel to almost any place between Mun and Kerbin. In this shot, it is docked at the Orbital Propellant Depot i found on this forum a few days ago. (Thanks to the creator ... don't know the name yet. ;-)) It is definetely not the most beautiful build, but it works as planned and is very fuel efficient. .craft File Greetings from Kerbal orbit
