- using a dolly to move a truss of a type that hangs a light;
- placing the light on the truss and placing the truss on the dolly with the light attached to the truss;
- and
- folding the dolly after using the dolly to move the truss,
- wherein said folding comprises moving a truss holding arm between a first position in which there is a channel structure that faces substantially vertically, and a stowed position where said channel structure faces in a direction where said channel structure can not hold said truss in said channel structure, and wherein, in said stowed position, said channel structure is closer to a main surface of the frame relative to said first position.

A method comprising:
- using a dolly to hold a truss of a type that has surfaces that allow hanging a light;
- attaching a light to the truss on the dolly;
- and moving the truss in a way to make the truss rotate relative to the dolly;

A method comprising using a first dolly to hold a first truss of a type that has surfaces that allow hanging a light;
- attaching plural lights to the first truss on the first dolly;
- using an additional dolly to hold an additional truss of a type that has surfaces that allow hanging a light;
- attaching plural lights to the additional truss on the additional dolly;
- and
- stacking said first dolly with said first truss and said plural lights on said second dolly with said second truss and said plural lights such that said first truss stacked on said first dolly, said additional dolly stacked on the truss, and said additional truss is stacked on said additional dolly;
- and
- folding said truss, wherein said folding comprises moving a truss holding arm between a first position in which there is a channel structure that faces substantially vertically, and a stowed position where said channel structure faces in a direction where said channel structure can not hold said truss in said channel structure, and wherein, in said stowed position, said channel structure is closer to a main surface of the frame relative to said first position.
