a pivot joint that connects the drag brace connection member of the fixed truss structure to the drag brace,
wherein the drag brace comprises an upper drag brace and a lower drag brace,
the upper drag brace has a first end configured to be pivotably attached to a first structural portion of a vehicle, and a second end that is pivotably attached to the lower drag brace,
the lower drag brace has a first end that is pivotably attached to the second end of the upper drag brace, and a second end that is pivotably attached to the drag brace connection member of the fixed truss structure,
the drag brace is configured to move between a deployed position and a stowed position,
the vehicle structure connection point of the fixed truss structure is configured to pivotably attach to a second structural portion of the vehicle,
in the stowed position, a longitudinal axis of the upper drag brace and a longitudinal axis of the lower drag brace are in a first relative position in which the longitudinal axes are not colinear, and
