Claim 10:
11. A trailer comprising:
a trailer bed frame assembly comprising at least first and second frame sections hingedly connected together and pivotal between a folded configuration wherein the at least first and second frame sections extend in overlapping alignment and an unfolded configuration wherein the at least first and second frame sections extend in planar alignment; when said at least first and second frame sections are positioned in the unfolded configuration, the trailer bed frame assembly having left and right sides each having front and rear ends;
left and right tension member supports connected to and extending upward from the left and right sides respectively of the trailer bed frame assembly in the unfolded configuration and positioned medially between the respective front and rear ends of the left and right sides;
a left, front tension member supported at an inner end on the left tension member support in spaced relation above the trailer bed frame assembly and connected at a forward end to a left side of the trailer bed frame assembly forward of the left tension member support;
a left, rear tension member supported at an inner end on the left tension member support in spaced relation above the trailer bed frame assembly and connected at a rearward end to a left side of the trailer bed frame assembly rearward of the left tension member support;
a right, front tension member supported at an inner end on the right tension member support in spaced relation above the trailer bed frame assembly and connected at a forward end to a right side of the trailer bed frame assembly forward of the right tension member support; and
a right, rear tension member supported at an inner end on the right tension member support in spaced relation above the trailer bed frame assembly and connected at a rearward end to a right side of the trailer bed frame assembly rearward of the right tension member support; and
left and right wheels rotatably mounted on left and right suspensions removably securable to the left and right sides respectively of the trailer bed frame wherein the left and right suspensions each comprise quarter elliptical leaf spring assemblies.
