With the reveal of the Dragon V2 (Or is it Dragon 2 now? Or Dragonrider?) we saw a new trunk design where the solar panels are wrapped around the trunk instead of being deployed like wings from the cargo version of the trunk.
If so, will the new trunk still carry unpressurized cargo to the station? Or will the available space be used for different purposes? (Batteries? Abort fuel tanks? Consumables?)
Additionally, if it does, can the CanadArm reach around and into the trunk, when it is docked on the PMA-2 Node-2 forward? How about PMA-3 Node - 2 Nadir (once it is moved).
