In terms of a missions that might involve retrieving, a rover, and then redeploying at another location...
How much success have you all had with using the cargo ramp on an airplane?
Design-wise I have a nice little cargo plane, loading ramp attached to the big Mk3 cargo bay. Loads and unloads a refueling truck on the KSC runway just fine. ...but then I fly with it over to the island runway and try to unload it (undock it ) and the truck seems to be damaged by the flight or landing? I've tried different connectors and seem to get the same issue. In flight the thing gets damaged and/or the wheels merge with the fuselage or something? ...and I can't disembark the rover again once at the island, or if I can the wheels/motors are damaged and it doesn't want to move. I even raised the deck of the cargo bay to give the wheelbase a little more width (I thought it was a clipping issue with the curved sidewalls) and I continue having the problem.
I also notice that during the flight, the plane controls are translated into the rover, so it's back there in the cargo bay with wheels going and steering active. Disabling the docking port crossfeed seems to do nothing in this regard.
