Kerbal Space Program

The extendable ladder has an automatically generated drag-cube corresponding to its container, which is clipped inside the craft by default. The shape of the (usually hidden) box and KSPs rules for drag of surface mounted parts means that the ladder contributes more drag to a rocket than a 1-man pod.

The ladders' configuration files could specify dimensions so only the usually-exposed part of the container contributes to drag:
