based on this : https://robertsspaceindustries.com/media/rsmrf96ceweoir/source/Crusader-Hercules-Starlifter.pdf The C2 variant carry 624 SCU the M2 variant carry 468 SCU however, both ships carry the same amount of vehicles, Only difference is, the M2 has got "heavy" armour, same as Starfarer Gemini, and C2 has got "medium armour", same as starfarer. How would that explain the difference between 624 and 468 SCU? Is the cargo bay height reduced by armor? Or is it simply a weight limit?
