This is a 1950 Dodge Power Wagon swivel chassis. It is powered by a 230 cubic inch (3.8L) flathead inline-six, making 92-94 horsepower and 185-190 pound-feet of torque. It has a 4-speed manual transmission and has a manual 4x4 switch, aka low gear and high gear.

I took some wheels off of Jacob Wiese's wpl off road wheels studded tire (thank you) and put them on the truck.
