The present invention is directed to apparatus, systems, and methods for distributing the weight of a trailer to a towing vehicle and controlling the sway of that trailer relative to the towing vehicle. An embodiment of the present invention includes a spring arm coupled to the towing vehicle and an attachment mechanism for selectively placing the spring arm in mechanical communication with the trailer. The attachment mechanism includes a bracket assembly reversibly attachable to the trailer; a shoe bracket reversibly attachable to the bracket assembly; and a friction pad coupled to the shoe bracket.

1. A system for distributing the weight of a trailer to a towing vehicle and controlling the sway of the trailer relative to the towing vehicle, the system comprising: a spring arm coupled to the towing vehicle; andan attachment mechanism for selectively placing the spring arm in mechanical communication with the trailer, the attachment mechanism comprising: a bracket assembly attachable to the trailer a side bracket having a first plurality of apertures therein, a bottom bracket having a second plurality of apertures selectively alignable with the first plurality of apertures, and a fastener connecting one of the first plurality of apertures to one of the second plurality of apertures to selectively connect the side bracket to the bottom bracket;a shoe bracket attachable to the bracket assembly; anda friction pad rigidly coupled to the shoe bracket, wherein the friction pad remains vertically stationary relative to the shoe bracket during operation. 2. The system of claim 1, wherein the spring arm is selectively in contact with the friction pad. 3. The system of claim 2, wherein the spring arm is in mechanical communication with the trailer through a force applied to the friction pad by the spring arm. 4. The system of claim 1, wherein the shoe bracket includes an aperture. 5. The system of claim 4, wherein the shoe bracket is attachable to the bracket assembly by the fastener being selectively passed through the first or second plurality of apertures of the bracket assembly and the aperture of the shoe bracket. 6. The system of claim 5, wherein the shoe bracket is attachable to the bracket assembly at a plurality of locations along the bracket assembly. 7. The system of claim 1, wherein the shoe bracket may selectively be secured to the side bracket and bottom bracket at a plurality of locations. 8. The system of claim 7, further comprising a cover selectively attachable to the shoe bracket while the spring arm is supported by the shoe bracket. 9. The system of claim 1, wherein the shoe bracket includes a third aperture and the fastener may be selectively passed through the first aperture, the second aperture, and the third aperture to secure the shoe bracket to the side bracket and the bottom bracket. 10. The system of claim 9, wherein the shoe bracket may rotate about the fastener. 11. The system of claim 1, wherein the attachment mechanism is securable to the trailer at a plurality of locations along the trailer. 12. The system of claim 1, wherein a first surface of the bracket assembly is in contact with a top surface of the trailer, a second surface of the bracket assembly is in contact with a bottom surface of the trailer, a third surface of the bracket assembly is in contact with a first side surface of the trailer, and a fourth surface of the bracket assembly is in contact with a second side surface of the trailer when the bracket assembly is attached to the trailer. 13. The system of claim 1, wherein the bracket assembly further comprises a top bracket connected to the side bracket. 14. A method of distributing the weight of a trailer to a towing vehicle and controlling the sway of the trailer relative to the towing vehicle, the method comprising: coupling a spring arm to the towing vehicle;selectively placing the spring arm in mechanical communication with the trailer via an attachment mechanism, wherein the attachment mechanism includes a bracket assembly attachable to the trailer and a shoe bracket attachable to the bracket assembly, wherein the bracket assembly comprises a top bracket, a side bracket connected to the top bracket, the side bracket having a first plurality of apertures therein, and a bottom bracket having a second plurality of apertures selectively alignable with the first plurality of apertures;connecting one of the first plurality of apertures to one of the second plurality of apertures via a fastener to selectively connect the side bracket to the bottom bracket;coupling a friction pad to the shoe bracket; andsubstantially horizontally pivoting the shoe bracket about the fastener as the spring arm moves relative to trailer. 15. The method of claim 14, wherein the attachment mechanism is selectively attachable to the shoe bracket. 16. A system for distributing the weight of a trailer to a towing vehicle and controlling sway of the trailer relative to the towing vehicle, the system comprising: a spring arm coupled to the towing vehicle;a bracket assembly attachable to the trailer comprising a side bracket and a bottom bracket;a fastener connecting the side bracket to the bottom bracket;a shoe bracket attachable to the bracket assembly; anda sleeve located around the fastener, wherein the sleeve facilitates substantially horizontal pivoting of the shoe bracket about a central axis of the fastener. 17. The system of claim 16, wherein the sleeve is aligned with an aperture of the shoe bracket. 18. The system of claim 16, wherein the pivoting about the central axis permits the shoe bracket to be variably positioned to maintain contact with the spring arm to enhance the sway control of the trailer.
