Yeah, I orginally designed it with the SSB4.0 nuclear reactor dragging off the back but thought that seemed excessive. The mission plan is not to leave the mothership at all if they can help it. I'd be more worried about the microgravity environment....
Having the habitat be detachable gives some flexibility to the architecture as an identical mothership can also preplace propellants for return or landers or stations or what have you and not hold your "piloted" and "cargo" vehicles to different standards. Then it might make sense to have the crew hooked up to something else.
Right now I'm working on a "cargo trailer" headed by a modified truss element with a docking port replacing one of the construction ports since I like the aesthetic of how the cargo grapples slot over the truss when it is docked lengthwise
