Just got off work early and see that it's launched finally. Amazing work!!!
PS: The Taxi still a 2 stage lander, right? And why do the variants have different RCS blocks?
I think he's talking about ETS's Saturn V (II). IIRC it was Robert Zubrin's proposal for Mars Direct in the timeline. Imagine a Saturn Multibody with 5 core stages synchronized together, a modernized S-II and a S-IVC to launch the hab and ERV.

This one is for @Bealeand @CobaltWolf for giving us proper (Re)Stockalike real world spacecraft. May not be an exact docking module, but still looks great.
PS: I got Apollo into orbit with MJ's PVG with just 2 m/s of DV.
