This page tracks progress of instructions for the extended 42009 Mod. Jurgen Krooshoop did the "Ultimate 42009" fully motorized and most of his superstructure is preserved here. Christophe Moittie did a wonderful extended boom. Finally, Gerger totally redesigned the carrier to have 6 axles all driven, suspended, and 5 steered. I converted the LDD file to LDraw, and various people are now at work making instructions.
