A firefighting vehicle includes a chassis, a front wheel assembly coupled to the chassis and having at least one front wheel defining an axis of rotation that is substantially perpendicular to the chassis when in a straight position, an operator cab positioned at a front portion of the chassis, and an engine supported by the chassis. The operator cab has a floor section extending laterally between a driver seat and a passenger seat at a position forward of the axis of rotation, and the floor section is substantially flat. The engine is disposed under the operator cab and at least partially rearward of the axis of rotation.
