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 having a modulus of elasticity, the moment bar comprising:
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;

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 has a modulus of elasticity less than 15,000 ksi.
