The support members are movable on the chassis between a first position at which the wheels are located within the tracking width of the vehicle and at which the wheels are aligned with the direction of travel of the vehicle, and a second position at which the wheels are displaced laterally from the tracking width to provide access to the rear of the chassis. First and second dielectric regions respectively adjoin opposing lateral sidewall portions of the drift region. Prior to welding, the fitting may have an annular lip immediately surrounding the surface of the pipe and may also have a ring spaced from the lip.
