Abstract
A cargo transport rear frame includes a pair of posts, an upper cross member, and a rear bolster. The posts are spaced in a width direction, and extend in a height direction. The upper cross member extends along the width between the posts. The rear bolster extends between lower ends of the posts such that the rear bolster is spaced below the upper cross member. The posts, the upper cross member, and the rear bolster bound the rear cargo opening. The rear bolster has a first side facing in a forward direction, and the rear bolster has a second side facing in a rearward direction to be exposed to a rear side of the cargo transport rear frame. The rear bolster comprises a sheet metal stamping including a base surface and a relief embossed in the rearward direction from the base surface to form a loading dock engagement feature.
