The images below depict a 350 VNT Payhauler model converted from an International Payhauler 350 model kit. 

Putting a steer axle on both ends and relocating the operators compartment to mid ship was all that was required to make a Vector Neutral Truck. 

The radiator has been relocated to reduce over all length.

The International Harvester Payhauler 350 was first built in the 1960s, Payhauler was sold to Terex in 1998.
