Conversion to cargo configuration will involve taking out the seats, crew consoles, life support, and etc. Essentially it means unbolting, unplugging, and removing components that simply aren't needed. And adding the structural supports for cargo. (aka glorified shelves/racks or whatever). However, if the insides of the Dragon are re-usable easily and not damaged by a flight/landing, why go through the trouble of changing in inside config from a crewed one proven to work to a cargo one ? It isn't just the "bolted on" consoles, but also all wiring harnesses. I wonder if Musk/SpaceX will ever explain what arguments were used to decide that crewed shouldn't be re-usable as crewed. NASA is always conservative (other than crewed STS-1 :-) So my guess is it ultimately came down to: "because we said so" and everything else was justification for that. And my guess is after 3-4 flights, NASA will relent and go with a refurbished crew capsule. This was apparently a SpaceX decision and not driven by NASA. NASA offered both SpaceX and Boeing the option of reflying capsules. Boeing plans to do so, flying each crew capsule up to ten times. SpaceX decided not to do that for their own internal reasons. The Boeing capsule is going to land on land while SpaceX is going in the water. That difference in refitting costs may be the difference, although SpaceX plans to refly Crew Dragons as cargo carriers after their single manned flight. -- "The reasonable man adapts himself to the world; the unreasonable man persists in trying to adapt the world to himself.
