A proof of concept model of the futuristic mobile command center, "The Winnebago", from the "Shadowside" project.
The specific idea behind this concept is that the vehicle is more an urban unit, perhaps intended for police use or VIP transport, rather than strictly a military APC. Thus, it is conceived not so much an ATV as a massive road vehicle.
Its dimensions have been intentionally rendered somewhat oversized by conventional standards to emphasize a sense of intimidating brutality, even when the vehicle sits immobile.
