1. An appliance-support system comprising a truss adapted to support an appliance, the truss having an outer frame and cross bars coupled to the outer frame, anda rolling base coupled to the truss, the rolling base including a first support frame extending along a first side of the truss and a second support frame extending along a second side of the truss opposite the first side, each of the first and second support frames including a pair of spaced apart legs, each leg having a proximal end coupled to the truss to allow pivoting movement of the leg relative to the truss and a distal end spaced apart from the proximal end,wherein the rolling base is movable relative to the truss between an expanded-use position where the first and second support frames extend downward from the truss and a collapsed-storage position where the first and second support frames are stored substantially within the outer frame, and the legs of the first support frame rotate toward one another and the legs of the second support from rotate toward one another with movement of the rolling base from the expanded-use position to the collapsed-storage position. 2. The system of claim 1, wherein each of the first and second support frames further includes a pair of wheeled supports, one of the wheeled supports coupled to the distal end of one leg of the pair of legs and the other wheeled support coupled to the distal end of the other leg of the pair of legs. 3. The system of claim 2, wherein each leg is configured for telescopic movement to adjust a length of the leg. 4. The system of claim 2, further comprising mount blocks coupled to the truss, and wherein the legs are coupled to the mount blocks for pivoting movement relative to the truss. 5. The system of claim 4, wherein the wheeled supports are configured to engage mount blocks of a secondary appliance-support system to form a stack of appliance-support systems when the rolling base is in the expanded-use position. 6. The system of claim 2, wherein each of the first and second support frames further includes: a pair of sliders, one slider coupled to one leg of the pair of legs and the other slider coupled to the other leg of the pair of legs, each slider configured to move along the respective leg, anda connecting rod coupled to the sliders. 7. The system of claim 6, wherein the connecting rod includes an outer tube and an inner tube at least partially received in the outer tube and configured for telescopic movement relative to the outer tube. 8. The system of claim 6, further comprising a latch coupled to the truss and configured to receive the connecting rod when the rolling base is in the collapsed-storage position. 9. The system of claim 6, wherein each pair of sliders is configured to rotate relative to the respective connecting rod with movement of the rolling base between the expanded-use and collapsed-storage positions. 10. The system of claim 6, wherein each pair of sliders is configured to move along the respective pair of legs toward the proximal ends of the respective pairs of legs with movement of the rolling base from the expanded-use position to the collapsed-storage position. 11. The system of claim 1, further comprising stacking pins coupled to the truss and configured to engage a secondary appliance-support system to form a stack of appliance-support systems. 12. The system of claim 11, wherein the stacking pins are configured to engage with pin holes of the secondary appliance-support system when the rolling base is in the collapsed-storage position. 13. An appliance-support system comprising a truss adapted to support an appliance, the truss having an outer frame and cross bars coupled to the outer frame, anda rolling base coupled to the truss, the rolling base including a first support frame extending along a first side of the truss and a second support frame extending along a second side of the truss opposite the first side, each of the first and second support frames including a pair of spaced apart legs, each leg having a proximal end coupled to the truss to allow pivoting movement of the leg relative to the truss and a distal end spaced apart from the proximal end,wherein the rolling base is movable relative to the truss between an expanded-use position where the first and second support frames extend downward from the truss and a collapsed-storage position where the first and second support frames extend along an underside of the truss, and the legs of the first support frame rotate toward one another and the legs of the second support from rotate toward one another with movement of the rolling base from the expanded-use position to the collapsed-storage position. 14. The system of claim 13, wherein each of the first and second support frames further includes a pair of wheeled supports, one of the wheeled supports coupled to the distal end of one leg of the pair of legs and the other wheeled support coupled to the distal end of the other leg of the pair of legs. 15. The system of claim 14, wherein each leg is configured for telescopic movement to adjust a length of the leg. 16. The system of claim 14, further comprising mount blocks coupled to the outer frame, and wherein the legs are coupled to the mount blocks for pivoting movement relative to the truss. 17. The system of claim 16, further comprising braces coupled to the outer frame and coupled to the legs to block rotation of legs relative to the truss when the rolling base is in the expanded-use position. 18. The system of claim 16, wherein the rolling base extends along the outer frame outside of the outer frame when the rolling base is in the collapsed-storage position. 19. The system of claim 16, further comprising sockets coupled to the frame, and wherein each of the legs are configured to be removed from the mount blocks and received in the sockets such that the rolling base extends from an opposing side of the truss from the mount blocks to support the truss. 20. The system of claim 14, wherein each of the first and second support frames further includes: a pair of sliders, one slider coupled to one leg of the pair of legs and the other slider coupled to the other leg of the pair of legs, each slider configured to move along the respective leg, anda connecting rod coupled to the sliders. 21. The system of claim 20, wherein the connecting rod includes an outer tube and an inner tube at least partially received in the outer tube and configured for telescopic movement relative to the outer tube. 22. The system of claim 20, wherein each pair of sliders is configured to rotate relative to the respective connecting rod with movement of the rolling base between the expanded-use and collapsed-storage positions. 23. The system of claim 20, wherein each pair of sliders is configured to move along the respective pair of legs toward the proximal ends of the respective pairs of legs with movement of the rolling base from the expanded-use position to the collapsed-storage position. 24. An appliance-support system comprising a truss adapted to support an appliance, anda rolling base coupled to the truss, the rolling base including a first support frame extending along a first side of the truss and a second support frame extending along a second side of the truss opposite the first side, each of the first and second support frames comprising: a pair of spaced apart legs, each leg having a proximal end coupled to the truss to allow pivoting movement of the leg relative to the truss and a distal end spaced apart from the proximal end,a pair of sliders, one slider coupled to one leg of the pair of legs and the other slider coupled to the other leg of the pair of legs, each slider configured to move along the leg,a connecting rod coupled to the sliders, anda pair of wheeled supports, one wheeled support coupled to the distal end of one leg of the pair of legs and the other wheeled support coupled to the distal end of the other leg of the pair of legs,wherein the rolling base is movable between an expanded-use position where the legs extend downward from the truss and a collapsed-storage position where the legs extend along the truss, and the legs of the first support frame rotate toward one another and the legs of the second support from rotate toward one another with movement of the rolling base from the expanded-use position to the collapsed-storage position. 25. The system of claim 24, further comprising a keyway coupled to each leg, and wherein the keyways are configured to block rotation of the sliders relative to the legs. 26. The system of claim 24, wherein each leg is formed as a substantially square tube, and wherein each slider is configured to engage with the legs to block rotation of the sliders relative to the legs.
