  • Aerodynamically streamlined step assembly for a truck
    Patent number: 4836568
    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.
