1. A transport dolly comprising: a base including a generally horizontal platform adapted to support an object to be moved, the platform including a bottom surface and a flat continuous top surface having side edges, the base further including generally vertical side walls that extend downward from each of the side edges of the top surface toward a floor or ground surface; andcasters mounted to the bottom surface of the platform between the side walls, the casters and the side walls being dimensioned such that bottom edges of the side walls nearly touch the floor or ground surface on all sides of the base such that the casters are enclosed and protected by the side walls on all sides of the transport dolly. 2. The dolly of claim 1, wherein base, including its platform and side walls, is made from a single piece of material. 3. The dolly of claim 2, wherein the base is made of a single sheet of steel that has been folded to form the platform and side walls. 4. The dolly of claim 1, wherein the platform comprises multiple openings adapted to receive a removable vertical post. 5. The dolly of claim 4, wherein the openings are positioned near the edges of the top surface of the platform. 6. The dolly of claim 4, wherein the base further comprises a support structure associated with each opening in the platform, each support structure being adapted to support a vertical post that has been inserted into an associated opening. 7. The dolly of claim 6, wherein the support structures each comprise a bracket positioned on an inner side of a side wall and a lip that extends inward from the bottom edge of the side wall, wherein the post passes through the bracket and is supported by the lip. 8. The dolly of claim 1, wherein the side walls comprise multiple openings adapted to receive a removable horizontal post. 9. The dolly of claim 8, wherein the openings are positioned near top edges of the side walls. 10. The dolly of claim 8, wherein the side walls further comprise openings adapted to receive tie-down straps. 11. The dolly of claim 1, further comprising wheels mounted to opposed side walls of the base. 12. The dolly of claim 11, wherein the wheels are mounted to the side walls such that the wheels do not contact the floor or ground surface when the surface is even. 13. The dolly of claim 1, wherein the horizontal platform is devoid of any components that extend above its flat, continuous upper surface. 14. The dolly of claim 1, wherein the horizontal platform excludes rollers that would enable the object to roll off of the top surface. 15. A transport dolly comprising: a base including a generally horizontal platform adapted to support an object to be moved, the platform having a flat continuous top surface having multiple side edges, a bottom surface, and multiple openings positioned near the side edges adapted to receive a removable vertical post, the base further including generally vertical side walls that extend downward from each of the edges of the top surface toward a floor or ground surface; andcasters mounted to the bottom surface of the platform between the side walls, the casters being dimensioned such that bottom edges of each of the side walls nearly touch the floor or ground surface on all sides of the base such that the casters are enclosed and protected by the side walls on all sides of the transport dolly. 16. The dolly of claim 15, wherein base, including its platform and side walls, is made from a single sheet of steel that has been folded to form the platform and side walls. 17. The dolly of claim 15, wherein the base further comprises a support structure associated with each opening in the platform, each support structure being adapted to support a vertical post that has been inserted into an associated opening. 18. The dolly of claim 17, wherein the support structures each comprise a bracket positioned on an inner side of a side wall and a lip that extends inward from the bottom edge of the side wall, wherein the post passes through the bracket and is supported by the lip. 19. The dolly of claim 15, further comprising wheels mounted to opposed side walls of the base, wherein the wheels are mounted to the side walls such that the wheels do not contact the floor or ground surface when the surface is even. 20. The dolly of claim 15, further comprising removable posts that can be inserted into and removed from the openings and support structures. 21. The dolly of claim 20, wherein the side walls comprise multiple openings adapted to receive a removable horizontal post, wherein the removable posts can be inserted through the openings of the side walls. 22. The dolly of claim 15, wherein the top surface of the platform is no more than 6 inches above the floor or ground surface and the bottom edges of the side walls are spaced no more than 20 millimeters from the floor or ground surface. 23. The dolly of claim 15, wherein the horizontal platform is devoid of any components that extend above its flat, continuous upper surface. 24. The dolly of claim 15, wherein the horizontal platform excludes rollers that would enable the object to roll off of the top surface.
