A support arrangement for a haul truck comprises a space frame and a dump body operatively positioned on the space frame according to defined contact points. The space frame can include at least one rear support, at least one outer elongate support member, and at least one support rocker configured to pivot laterally about an axis. The dump body can include on a bottom thereof a rear pivot support and at least one flat contact surface, and on a front face thereof at least one vertical support structure. Each rear support of the space frame is configured to be pivotally coupled to the rear pivot support of the dump body. Each vertical support structure of the dump body is configured to be removably seated in a corresponding support rocker. Each flat contact surface is configured to be positioned adjacent to an outer lateral surface of an outer elongate support member.

An embodiment vehicle body includes a drive vehicle body module configured to accommodate a driving part of a vehicle and including a first plurality of frames coupled together and fastening units provided at an upper end of the drive vehicle body module and an upper vehicle body module including a second plurality of frames coupled together, wherein a lower end of the upper vehicle body module is fastened to the fastening units of the drive vehicle body module to define an interior usage space of the vehicle.

A vehicle body side structure of the present invention includes: a floor cross member that is connected to a side sill and that extends in a vehicle width direction; and a bulk head that partitions a closed cross section of the side sill in a vehicle body front-rear direction, at the side of the floor cross member in the vehicle width direction. The bulk head includes a partition wall that partitions the closed cross section in the vehicle body front-rear direction and a flange that extends from an edge portion of the partition wall in both of a vehicle body front direction and a vehicle body rear direction and that is formed over an entire periphery of the edge portion of the partition wall. The flange is connected to the floor cross member with the side sill in between.
