Abstract: A truck cab including entry doors on either side, a fender below and spaced in front of each entry door, and a fuel tank below and spaced behind each entry door is disclosed herein. The cab also includes aerodynamic step assembly which is located on each side of the cab below the entry door on that side and which contains a readily accessible tool or battery box. This box and the steps leading to the entry door are no wider than the door itself and therefore are spaced from the adjacent fender and fuel tank. However, aerodynamically shaped panels form part of the overall assembly for closing these spaces.

Abstract: A vehicle of the type having a manual transmission is disclosed herein. The manual transmission includes a clutch, a clutch pedal and a linkage assembly interconnecting the clutch with the pedal and requires that the driver of the vehicle depress the clutch pedal in order to disengage the clutch. There is also disclosed herein an arrangement for assisting the driver in disengaging the clutch when the clutch pedal is depressed. This arrangement includes a power assist device, a source of power for driving the device, and a valve assembly including a valve and mounting components interconnecting the valve with the transmission's linkage assembly such that the manual depression of the pedal by the driver automatically acts on the valve to cause the latter to connect the power assist device to its source of power in order to drive the device and therefore aid the driver in disengaging the clutch.
