Abstract
A trailer frame includes a rear bolster, cross-members, and corner gussets extending forwardly from ends of the rear bolster. A rear impact guard includes a bumper positioned at the rear end of the trailer and spaced below the rear bolster, pair of outboard posts, and at least one inboard post. The outboard posts extend between the bumper and the rear bolster adjacent respective opposed distal ends of the bumper, and the inboard post extends between the bumper and the rear bolster between the outboard posts. Each of the pair of outboard posts has a lower end that overlaps with a respective mounting bracket that protrudes upwardly toward the rear bolster from the bumper such that mounting holes of the outboard posts align with mounting holes of the mounting brackets. A laterally-outboard panel of each mounting bracket extends obliquely from the bumper in a direction with a laterally-outward component.
