A trailer includes a floor engageable with a load and a longitudinally extending support member. The support member has an upper portion connected to the floor, a lower portion connectable to a suspension system, and a web extending between the upper and lower portions and transverse to the floor. The lower portion has a lower flange extending transverse to the web and connectable to the suspension system. The lower flange has a first portion extending from a first side of the web a first distance and a second portion extending from a second opposite side of the web a second distance larger than the first distance.

Having described the invention, I claim: 1. A trailer comprising: a floor engageable with a load, the floor comprising a plurality of tubular portions; a first longitudinally extending support member, the first support member having an upper portion connected to the floor, a lower portion connectable to a suspension system, and a web extending between the upper and lower portions and transverse to the floor, the lower portion having a lower flange extending transverse to the web and connectable to the suspension system, the lower flange having a first portion extending from a first side of the web a first distance and a second portion extending from a second opposite side of the web a second distance greater than the first distance, the first and second distances being greater than approximately five inches combined; and at least a pair of support brackets for securing the load; wherein the tubular portions extend transverse to a longitudinal axis of the first support member; and wherein said tubular portions comprise four tubular portions defined by an upper wall, a lower wall, two side walls, and three partitioning walls, and wherein the outermost two of the three partitioning walls extend above the upper wall and form inward-facing hooks for receiving the at least one pair of support brackets. 2. A trailer as set forth in claim 1 wherein the second distance is three times greater than the first distance. 3. A trailer as set forth in claim 1 further including a second longitudinally extending support member for the floor, the second support member extending generally parallel to the first support member, the second support member having an upper portion connected to the floor, a lower portion connectable to a suspension system, and a web extending between the upper and lower portions and transverse to the floor, and the lower portion of the second support member having a lower flange extending transverse to the web and connectable to the suspension system, the lower flange of the second support member having a first portion extending from a first side of the web of the second support member a first distance and a second portion extending from a second opposite side of the web of the second support member a second distance greater than the first distance, the first and second distances of the lower flange of the second support member being greater than approximately five inches combined. 4. A trailer as set forth in claim 3 wherein the second portion of the lower flange of the first support member extends toward the second support member and the second portion of the lower flange of the second support member extends toward the first support member. 5. A trailer as set forth in claim 1 wherein the upper portion of the first support member includes an upper flange connected to the floor, the upper flange extending transverse to the web. 6. A trailer as set forth in claim 1 wherein the upper portion of the first support member has an upper surface, the floor engaging the upper surface. 7. A trailer as set forth in claim 1 wherein the floor has a lower surface engaging the upper surface of the support member, the floor having a plurality of tubular portions extending transverse to a longitudinal axis of the first support member. 8. A trailer as set forth in claim 1 wherein the first distance is approximately two to three inches and the second distance is approximately six to ten inches. 9. A trailer as set forth in claim 1 wherein the upper portion of the first support member has an upper surface, the load being engageable with the upper surface. 10. A trailer as set forth in claim 1 wherein the second distance is approximately three to five times greater than the first distance. 11. A trailer as set forth in claim 1 wherein the first support member is an extruded member. 12. A trailer comprising: a floor engageable with a load, the floor comprising a plurality of substantially rectangular floor sections, each floor section comprising an upper wall with two side edges, a front edge, and a rear edge; a substantially rectangular lower wall substantially parallel to the upper wall and extending to the side edges, front edge, and rear edge of the upper wall; two side walls coextensive with the side edges and lower wall and extending substantially perpendicular to the upper and lower walls; a plurality of partitioning walls extending substantially perpendicular to the upper and lower walls and substantially parallel to the side walls, wherein the partitioning walls, the upper wall, the lower wall, and the side walls define a plurality of tubular portions; a first longitudinally extending support member, said first support member having an upper portion connected to a bottom of the lower wall, a lower portion connectable to a suspension system, and a web extending between said upper and lower portions and transverse to said floor, said lower portion having a lower flange extending transverse to said web and connectable to the suspension system; and at least one pair of support brackets for securing said load; wherein said upper wall further comprises at least one pair of recesses for receiving said at least one pair of support brackets; and wherein the plurality of partitioning walls consists of three partitioning walls forming four tubular portions and wherein the outermost two of the three partitioning walls extend above the upper wall and form inward-facing hooks for receiving the at least one pair of support brackets. 13. A trailer, comprising: a plurality of floor sections having an upper wall, a lower wall, and one or more partitioning walls connecting the upper wall to the lower wall, at least one of said first partitioning walls extending angularly from and extending integral with the upper wall for receiving and holding in position one or more support brackets, a longitudinally extending support member, said support member having an upper portion connected directly to said lower wall of said plurality of floor sections, a lower portion connectable to a suspension system, and a web extending between said upper and lower portions, said lower portion having a lower flange extending transverse to said web and connectable to the suspension system. 14. The trailer of claim 13, wherein at least one other second partitioning wall extends angularly from and extends integral with the upper wall for receiving and holding in position one or more support brackets, said second partitioning wall extending angularly in an opposite direction from the first partitioning wall. 15. The trailer of claim 14, wherein each floor section has on a first outer side wall a tab and on an opposing second outer side wall a first recess, wherein when said floor is assembled, at least one tab on one of the floor sections is coupled to said at least one first recess on another floor section. 16. The trailer of claim 15, wherein said at least one tab is welded to said at least one first recess.
