These vehicular accessories are typically metal or composite platforms affixed beneath the doors of the specified pickup truck. They serve as an intermediate step between the ground and the vehicle’s cabin. For instance, a driver or passenger might use this addition to more easily enter or exit a Toyota Tundra, especially if the vehicle has a significant lift or larger tires.
The inclusion of these aftermarket components enhances accessibility, especially for individuals with limited mobility or shorter stature. They also provide a degree of protection against road debris impacting the vehicle’s lower panels. Historically, such additions have evolved from simple running boards to more stylized and functional designs catering to both practical needs and aesthetic preferences.
