What is claimed is:

1. A rear impact guard configured to be coupled to a rear end of a vehicle, comprising:
first and second bumper support members configured to be coupled to the rear end of the vehicle and spaced outwardly from a longitudinal axis of the vehicle;
third and fourth bumper support members configured to be coupled to the rear end of the vehicle, the third bumper support member being spaced outwardly of the first bumper support member and the fourth bumper support member being spaced outwardly of the second bumper support member; and
a horizontal bumper mounted to lower ends of the first, second, third, and fourth bumper support members;
wherein the first and second bumper support members have a first configuration, the third and fourth bumper support members have a second configuration, and the first configuration is different than the second configuration.

2. The rear impact guard of claim 1 , wherein the first configuration includes having a circular aperture in walls forming the first and second bumper support members and the second configuration includes having a triangular aperture in walls forming the third and fourth bumper support members.

3. The rear impact guard of claim 1 , wherein:
the first configuration includes the first and second bumper support members having a first upper length parallel to a longitudinal axis of the vehicle;
the second configuration includes the third and fourth bumper support members having a second upper length parallel to the longitudinal axis of the vehicle; and
the second upper length is greater than the first upper length.

4. The rear impact guard of claim 1 , wherein each of the third and fourth bumper support members includes a hollow, generally triangular prism member, wherein the triangular prism member includes first and second generally triangular-shaped faces, a vertical member, a horizontal member, and an angled member, and the vertical, horizontal, and angled members are each positioned between and coupled to outer edges of the first and second triangular-shaped faces.

5. The rear impact guard of claim 4 , wherein each triangular-shaped face includes a generally triangular-shaped aperture.

6. The rear impact guard of claim 5 , wherein each of the first and second bumper support members includes a hollow, generally triangular prism member, wherein the triangular prism member includes third and fourth generally triangular-shaped faces, a vertical member, a horizontal member, and an angled member, and the vertical, horizontal, and angled members are each positioned between and coupled to outer edges of the third and fourth triangular-shaped faces.

7. The rear impact guard of claim 6 , wherein each triangular-shaped face of the first and second bumper support members includes a circular aperture.

8. The rear impact guard of claim 1 , further including a tube stiffener located within an interior spaced of the horizontal bumper.

9. The rear impact guard of claim 1 , further including bumper mounts for mounting the first and second bumper support members to the horizontal bumper, each bumper mount comprising:
a c-shaped bracket configured to be positioned adjacent a top surface of the horizontal bumper; and
at least one finger or wall extending outwardly from the c-shaped bracket and configured to be coupled to a front surface of the horizontal bumper;
wherein the first and second bumper support mounts receive the c-shaped bracket within lower open ends thereof and at least one fastener extends through the c-shaped bracket and the lower open ends of the first and second bumper supports.
