Material handling solutions for a mobile conveyor vehicle are provided. In one aspect, a vehicle having an infeed and output conveyor is provided, one of the conveyors being mounted non-rotatably to the vehicle and positioned by rotation-in-place of the vehicle via four wheel steering. In another aspect, a dust control cover for a telescoping conveyor is provided, having a pair of flexible flaps which are parted by a plough-shaped chute which travels through a gap between the flaps and delivers material to the lower conveyor section.

The structural member may radiate heat from the fluid for example to melt snow on the vehicle structure.
