Thank you everyone! And thank you Blackbird, those your renders are the exact thing that I've wanted to make and share...but I can't make it.
For me this MOC is special and favorite despite some details are not like a real truck. Suspensions, center pillar in the box, front end of the wings, etc. Anyway, I can't wait for CAD instructions!
In my short driving test, u-joints were not damaged. Even when using basic remote for drive and steer. Due to heavy load, there is possibility that u-joints are snapped or 12L axle is twisted. Maybe needs custom heavy duty u-joints.
