1. A weight distribution hitch system, comprising:
a vehicle attachment member, comprising:
a forward end configured to rigidly attach to a vehicle, and
a rearward end extending rearwardly toward a trailer, the rearward end comprising:
an upper portion comprising a trailer attachment member configured to pivotally attach to a coupler of the trailer, and
a lower portion configured to receive a moment bar,
a moment bar forward end attached to the lower portion of the rearward end of the vehicle attachment member so as to prevent rotation about a horizontal axis, and
a moment bar rearward end;
a tension member comprising:
a top end configured to be supported by a frame member of the trailer, and
a bottom end configured to support the rearward end of the moment bar, and
wherein, when the tension member is in tension, it imposes an upward force on the moment bar rearward end, which, in turn, imposes a forward moment on the vehicle; and
wherein the moment bar is made from a fiber reinforced polymer composite.
