Seeing the evolution of projects is quite wonderful. This M1083 chassis has undergone quite the transformation. Aside from a little touch up paint, the intermediate axel was removed, rear springs have been swapped to independently controlled airbags, and front airbags have been installed to smooth out the ride. The habitat its attat hed to the modified dump bed which has a winch attatched to the front of the box, allowing him to drop the box in minutes. Additionally, the planetary gears in each hub have been eliminated. Now with a fixed hub, it provides a direct 1:1 ratio as opposed to the normal 2:1 wheel end reduction. Why? Since peak torque is achieved somewhere between 1400 and 1600 rpm, this thing can cruise at 65mph running 1550 rpm. The result is significantly higher mpg (11-12mpg) 🤯, cooler temps and substantually lower rpms. One could question the truck's ability to start out without reprogramming the transmission, but i assure you, this thing will get off the line just as easy as a stock model. In the event where the gearing isn't low enough to climb out of an obstacle in 1st, there are front and reat 15k 24v winches for such an occasion.
