A resilient or flexible skirt panel assembly having an integral bracing system. In operation, the bracing system need not attach to a trailer base rail. The innovation discloses straight, straight-angled and curved skirt panel orientations. Additionally, angled braces, “v-braces,” “v-wings,” and integral rib bracing mechanisms are disclosed. In aspects, the skirt panel and bracing mechanisms can absorb (or bend) under force while effectively having a “memory” to return to their original shape upon removal of the force. The skirt assembly can include a hem along the bottom edge of the skirt panel thereby enhancing performance and longevity of the assembly. Additionally, an “anti-skid” clamping assembly can be employed to connect the skirt assemblies to the trailer I-beam, base rail or cross-members.
