This color set is fixed for the truck and cannot be changes through mod shops (unless recoloring it through the Content Creator). The truck only comes in a dark green primary color for the chassis and external frames of the vehicle, along with a matte desert brown/tan secondary color for the flat surfaces of the truck. The interior of the cab is devoid of any standard interior elements, other than a set of dials, switches, race seats and other components derived from race-style interior.
Below the bed and between the wheels, some of the vital components, such as the oil tanks and the fuel tanks, can be seen, along with articulated bars and suspension springs for the axles. A set of winch cables derived from the Flatbed can be seen over it, which does not serve any purpose outside of scripted missions. The rear section is predominated by the large bed with metal bars and panels on the sides. The sides of the cab lacks any sort of doors, instead being accessed directly. The front end is predominated by a front defense with four rectangular lamps on it, while the upper section of the cab is protected by a meshed screen with four additional lamps on the roof.
The truck's design is mainly composed of exposed frames with welded panels on them. The Wastelander is depicted as a rusty flatbed truck, apparently recovered from salvage and modified with newer parts to make it fully operable. The Wastelander is heavily based on the "Mongo" Heist Truck concept from Fast Five, seen in the overall design and purpose.
