A support structure arrangement for a front wall of a dump body comprises a first vertical support structure and a second vertical support structure. The first and second vertical support structures can be elongate structural members spaced in a width direction from each other. Bottom portions of the first and second vertical support structures can form down-facing contact surfaces.

A front vehicle body reinforcing structure is provided to improve front collision response performance of a vehicle. The front vehicle body reinforcing structure includes a front side member that is disposed on each of left and right sides of a front vehicle body to extend in a front-rear direction of a vehicle body. A crossbar is installed to connect between the front side members on the left and right sides and has a form bent in a bow shape. Additionally, support brackets are installed to connect between left and right side portions of the crossbar and the front side members to support the crossbar at each of the front side members.

A vehicle support structure according to an exemplary aspect of the present disclosure includes, among other things, a cross-member of a vehicle support structure. The cross-member extends longitudinally along a cross-member axis. The frame assembly further includes a rail of the vehicle support structure. The rail extends longitudinally along a rail axis that is transverse to the cross-member axis. The rail extends into a pocket of the cross-member such that a portion of the rail is nested within the cross-member.

A front upper frame connection for a space frame can comprise a top surface; a bottom surface opposite the top surface; a right-side surface; a left-side surface opposite the right-side surface; a front surface; a rear surface opposite the front surface; a pair of forward support plates provided on the front surface; a pair of forward flat mounting surfaces; and a pair of rocker attachment interfaces located on the top surface adjacent to the rear surface and respectively the right-side surface and the left-side surface. The front surface and the forward support plates can define a cutout section. Each of the forward support plates is curved and runs outward from a transverse centerline of the top surface and then forward.

A vehicle body includes a rear pillar, a roof siderail, and a side inner panel. The rear pillar is disposed to a side of a rear hatch, and extends in an up-down direction. The roof siderail extends in a vehicle body front-rear direction at a side of a roof, and a rear end thereof is linked to the rear pillar. The side inner panel is linked to the rear pillar and the roof siderail. The roof siderail has a tubular shape, and bulges further into a vehicle cabin than an upper end of the side inner panel.
