In reference to the OP, I really like your designs and the idea is great. I've read the post several times, have gotten several different components down onto the Mun and I understand your solution for the docking ports not always matching up but for the life of me I can rarely get it to work within the first 15 minutes of trying. Even the small rover sitting directly under a docking port rarely seems to work. The only mods I am using are MechJeb and the Kethane mods.
