Yeah, Moonship in fact is actually slightly larger by 9m, but of course it's probably a good 60-70% by volume propellant, while the Roci's powerplant, drive, fuel, and reaction mass all combined probably make up only about 25% of it's internal volume, and it's drive has an ISP of something like 40,000s+ with a TWR high enough to accelerate up past 10 gees while carrying no significant mass of radiators.
