Dragon V2 specs

[sevenperforce]

I have been digging around online for a while and haven't really come up with much of anything, so I figured I would croudsource this. 

The Dragon V2 is listed with a dry mass of 6,400 kg.

Does that include crew amenities, like seats, displays, life support, that sort of thing?

What's the best estimate of how much of that mass is the trunk, how much is the heat shield, how much the SuperDracos weigh, how much the onboard fuel tanks weigh, the mass of the aeroshell and pressure vessel, and so forth? Can we use figures from Dragon 1 to estimate?

Dragon 1 is not even close I would think.

Not in absolute terms, no. Except for the trunk; the trunk probably weighs about the same. But more in relative/breakdown terms. For example, if we knew the mass of the Dragon 1 pressure vessel, we could use the square-cube law to estimate the mass of the DV2 pressure vessel.

Measuring the chute size and vertical speed on youtube "SpaceX pad abort test" we probably can estimate the landing mass.

Presuming that we know Superdracos full thrust and measuring vertical speed on start we probably can estimate the launch mass.

Measuring the above water part in the end of the movie we probably can estimate deadweight and inner volume.

Hmm, those figures might be attainable but you'd be measuring something that's pretty hard to figure out just from looking at it...
