1. A convertible hand truck comprising: a dual-use hand truck body with a first planar member that provides support for items on the hand truck when upright and that provides a table top when reclined 90 degrees;a dual-use load platform with a second planar member that provides a load bearing surface for loads on the hand truck when upright and that provides an extension of the table top when the hand truck is reclined 90 degrees; anda dual-use rack that provides support for items on the hand truck when the hand truck is upright and that provides support legs for the table top when the hand truck is, relative to its upright position, reclined 90 degrees;wherein the rack has a range of rotational motion of 180 degrees with the support legs being rotatable from a position perpendicular to a front surface of the first planar member to a position perpendicular to a back surface of the first planar member. 2. The hand truck of claim 1, wherein the table top comprises a first set of support legs disposed at a right angle relative to the first planar member and fixed at a first end of the table top and wherein the dual-use rack is disposed at an opposing second end of the table top and comprises a second set of support legs. 3. The hand truck of claim 1 further comprising a handle bar, wherein the handle bar is disposed at a right angle relative to arms of the rack to prevent further rotation of the rack arms beyond 90 degrees relative to the lower surface of the first planar member. 4. The hand truck of claim 2, further comprising wheels in operable communication with the first set of support legs. 5. The hand truck of claim 4, wherein the first set of support legs and wheels together provide a height to the first end of the table top that equals a height of the opposing second end of the table top provided by the second set of support legs. 6. A convertible hand truck comprising: a hand truck body with a first planar member and a first set of support legs disposed at a right angle relative to the first planar member and fixed at a first end of the hand truck body;wheels in operable communication with the first set of support legs;a load platform with a second planar member, which load platform is disposed at the first end of the hand truck body;means for connecting the load platform to the hand truck body to provide rotational movement of the load platform between 90-180 degrees away from the first planar member and to lock the load platform at 180 degrees relative to the first planar member;a rack disposed at an opposing second end of the hand truck body, which rack comprises a second set of support legs and a handle bar; andmeans for connecting the rack to the hand truck body to provide rotational movement of the rack and to lock the rack at right angles relative to the planar member;wherein the rack has a range of rotational motion of 180 degrees with the second set of support legs being rotatable from a position perpendicular to a front surface of the first planar member to a position perpendicular to a back surface of the first planar member. 7. The hand truck of claim 6 further comprising an umbrella hole. 8. The hand truck of claim 6, wherein the load platform comprises feet. 9. The hand truck of claim 6, wherein the second set of support legs comprise feet. 10. The hand truck of claim 6, which is less than twice as tall as it is wide. 11. The hand truck of claim 6 comprising metal. 12. The hand truck of claim 6, wherein the load platform has raised edges for securing items in tow. 13. The hand truck of claim 6, configured to support a load of 200-500 pounds. 14. The hand truck of claim 6, wherein the handle bar is disposed at a right angle relative to arms of the rack to prevent further rotation of the rack arms beyond 90 degrees relative to the lower surface of the first planar member. 15. The hand truck of claim 9, wherein the wheels and the second set of support legs are operably configured for supporting the table on sand in a manner to provide the first and second planar members parallel to the sand. 16. The hand truck of claim 15, wherein the wheels are 4-6 inches wide and the feet are at least two inches wide.
