This Technic MOC is built around a remotely controlled sequential gearbox with four speeds. You can build your own trailer and attach it to the functional fifth wheel. The truck's L-motor can comfortably pull a trailer in the first and second gears. Without load, you can speed it up by switching to the third and fourth gear. Driving, steering, and gear selection are all remotely operated by two Power Functions remote controls. Finally, the cabin is suspended and (optionally) fitted with PF lights.
