2 questions to make more clear how to rename the thread without scratching my head, and optionally whether to move it to another forum:
- Are you asking about just a spacecraft without launch vehicle, spacecraft + launch vehicle, or maybe just a launch vehicle without specified spacecraft?
- Does "mod of course" mean that you search only for add-ons excluding the vessels in the base Orbiter package?
Bonus question, already asked, if you weren't sure what you asked about: most fuel or most delta-v, or maybe both?
