Actually I did, may have gone a bit overboard with the supposed-to-be-rather-unnoticeable Duna textures that was supposed to be only seen while descending
Stick a girder thatis long enough to the center tank by clipping your camera into said tank, 2x the symmetry, then attach whatever you want on the sides.
Coverted the Orbiter to use LFO unlike the MP it used preciously, allowed me to cram a hell more dV than there was previously. The boosters work fine.Also, KSP tried to kill my Saturn V. Fixed that with 17 engines.
