Have I gone mad? maybe.
So. Apollo². Why land on the Moon once, when you can go to the Moon and back twice in one launch? And how about a Starship-style landing of a fully loaded Saturn V stack? Sounds fun, right?
Everything was done on the full RSS/RO suite of mods, in KSP 1.10.
Edited parts:
Re-entry: Because I don't have a proper mechanism to build TPS onto the Saturn V (or control large scale Starship-style flaps), "ignore max temp" was used during re-entry.
FAR Aerodynamic failures were also disabled.
The F1A was given an extra ignition, so that it could light for the flip and also for second launch.

Most of the mods can be found through the installation guide:
https://github.com/KSP-RO/RP-0/wiki/RO-&-RP-1-Installation-for-1.10.1
Nowadays it's pretty simple, RP-1 "express install" should give you most of them.
I also used DECQs Saturn V https://forum.kerbalspaceprogram.com/index.php?/topic/176505-12x13x14x-saturnv-v103-d160718/
Real scale sea dragon for the engines (modified by me to run on kerolox/hydrolox)
