A mounting assembly is provided for coupling an air drag reduction system to a trailer to be transported by an over-the-road tractor. The mounting assembly includes a frame to be suspended adjacent to an underside of the trailer, and a receiver supported adjacent to a first end of the frame. The receiver is adapted to cooperate with a portion of a structural member of the trailer when installed. An adjustable fastening mechanism is separated a suitable distance from the receiver along the frame to be positioned adjacent to a second portion of the structural member opposite the portion that cooperates with the receiver. The adjustable fastening mechanism includes a cam that is adjustable to make contact with the second portion of the structural member of the trailer, thereby interfering with separation of the receiver from the portion of the structural member of the trailer with which the receiver cooperates.

1. A mounting assembly for coupling an air drag reduction system to a trailer to be transported by an over-the-road tractor, the mounting assembly comprising: a frame to be suspended adjacent to an underside of the trailer;a receiver supported adjacent to a first end of the frame, wherein the receiver is adapted to cooperate with a structural portion of the trailer when installed; andan adjustable fastening mechanism separated a suitable distance from the receiver along the frame to be positioned adjacent to a second structural portion of the trailer, when installed, opposite the portion that cooperates with the receiver, the adjustable fastening mechanism comprising an adjustable cam and a leverage arm that is pivotally adjustable about an axis to urge the cam generally toward the second structural portion of the trailer and cause the cam to make secure contact with the second structural portion of the trailer, thereby interfering with separation of the receiver from the first structural portion of the trailer with which the receiver cooperates. 2. The mounting assembly of claim 1, wherein the secure contact between the cam and the second structural portion generates a force that urges the receiver toward the first structural portion with which the receiver cooperates. 3. The mounting assembly of claim 1, wherein the suitable distance separating the receiver from the cam is adjustable along a longitudinal axis of the frame. 4. The mounting assembly of claim 1, wherein the receiver comprises a channel in which a flange portion of a structural member forming the first structural portion is to extend. 5. The mounting assembly of claim 1 further comprising a base that is coupled to the frame and disposed between the frame and the fastening mechanism, wherein the leverage arm included as part of the fastening mechanism is pivotally coupled to the base to pivot about the axis of rotation relative to the base. 6. The mounting assembly of claim 5, wherein the base is adjustably coupled to the frame to be adjusted to a plurality of different positions along the frame, thereby adjusting the suitable distance separating the receiver from the cam along a longitudinal axis of the frame. 7. The mounting assembly of claim 5, wherein the fastening mechanism is adjustably coupled to the base to be adjusted to a plurality of different positions relative to the base, thereby adjusting the suitable distance separating the receiver from the cam along a longitudinal axis of the frame. 8. The mounting assembly of claim 1, wherein the cam included as part of the fastening mechanism is pivotally coupled to pivot about an axis of rotation relative to the frame. 9. The mounting assembly of claim 8, wherein the cam comprises a substantially-circular wheel formed from a substantially-elastically compressible material. 10. The mounting assembly of claim 9, wherein the suitable distance between the receiver and the wheel is sufficient to establish contact between the wheel and the second structural portion when the leverage arm of the fastening mechanism is pivoted about twenty)(20° degrees from a longitudinal axis of the frame. 11. The mounting assembly of claim 1 further comprising a locking device that interferes with pivotal adjustment of the leverage arm of the fastening mechanism relative to the frame. 12. The mounting assembly of claim 1 further comprising a fastening fixture adjustably coupled to the frame, wherein a position of the fastening fixture along the frame is adjustable. 13. The mounting assembly of claim 12, wherein the fastening fixture comprises a mounting substrate that extends downwardly from the frame. 14. The mounting assembly of claim 13 further comprising a fastener that releasably couples an airfoil to the mounting substrate. 15. The mounting assembly of claim 13, wherein the mounting substrate is coupled to the frame by a flexible connector that substantially-elastically deforms in response to being subjected to an impact. 16. A mounting assembly for coupling an air drag reduction system to a trailer to be transported by an over-the-road tractor, the mounting assembly comprising: a frame to be suspended adjacent to an underside of the trailer;a receiver supported adjacent to a first end of the frame, wherein the receiver comprises a channel with an aperture that is to receive a portion of a flange of a structural beam of the trailer when installed;a fastening mechanism that is pivotally coupled to the frame and is separated by an adjustable distance along the frame from the receiver, the fastening mechanism comprising a camming wheel that is pivotal about an axis of rotation and is positioned to contact another portion of the structural beam and urge the receiver towards the flange, wherein, a position of the axis of rotation is adjustable relative to the frame by pivotal adjustment of the fastening mechanism between a first position where the wheel initially makes contact with the another portion of the structural beam and a second position where the wheel is partially compressed against the another portion of the structural beam; anda locking device that interferes with pivotal adjustment of the fastening mechanism from the second position. 17. The mounting assembly of claim 16 further comprising a fastening fixture adjustably coupled to the frame, wherein a position of the fastening fixture along the frame is adjustable. 18. The mounting assembly of claim 16 further comprising a base that is coupled to the frame and disposed between the frame and the fastening mechanism, wherein the fastening mechanism is pivotally coupled to the base. 19. The mounting assembly of claim 18, wherein the base is adjustably coupled to the frame to be adjusted to a plurality of different positions along the frame, thereby adjusting the adjustable distance separating the receiver from the wheel along a longitudinal axis of the frame. 20. The mounting assembly of claim 18, wherein the fastening mechanism is adjustably coupled to the base to be adjusted to a plurality of different positions relative to the base, thereby adjusting the adjustable distance separating the receiver from the wheel along a longitudinal axis of the frame. 21. A mounting assembly for coupling an air drag reduction system to a trailer to be transported by an over-the-road tractor, the mounting assembly comprising: a frame to be suspended adjacent to an underside of the trailer;a receiver supported adjacent to a first end of the frame, wherein the receiver is adapted to cooperate with a portion of a structural member of the trailer when installed; andan adjustable fastening mechanism separated a suitable distance from the receiver along the frame to be positioned adjacent to a second portion of the structural member opposite the portion that cooperates with the receiver, wherein the suitable distance separating the receiver from the cam is adjustable along a longitudinal axis of the frame, the adjustable fastening mechanism comprising a cam that is adjustable to make contact with the second portion of the structural member of the trailer and thereby interfere with separation of the receiver from the portion of the structural member of the trailer with which the receiver cooperates.
