This is the tipper dump trailer that I built for my orange and black Peterbilt 389 http://rebrickable.com/mocs/motomatt/peterbilt-389-daycab-semi-truck-117-scale-in-black-and-orang. The tipper uses one PF m-motor for raising and lowering the dumper bed, and one PF m-motor for raising and lowering the landing gear. Raising the tipper bed is a pretty slow process and could take close to a minute.

A pair of linear actuators are used to directly lift the tipper bed. Unfortunately it would be rather difficult to replicate a more real-life accurate telescoping linear actuator attached above the fifth wheel, unless you had a 3D printed one available.

I built it in black and orange to match the Peterbilt 389, but it could also be done in yellow, or several other color variations.

It's fully functional but was designed to be used with relatively light loads. That means probably no loading with rocks or wet sand. The tipping geometry shown in the instructions is a fair compromise between a good tipping angle and maximum load which can be raised to dump out the back. You could easily customize the geometry to lean the balance in either more maximum angle, or more lifting ability. The tipper bed and framing walls are made to be as light as I could, so they can be rather flimsy when building and attaching together. The dumper floor has many holes to save weight, as the intention was to use a plastic trash bag to seal the inner dumper body. I simply cut a piece of a black plastic thrash bag which is attached to the tipper walls with 1 x 4 and 1 x 2 plates. I also used a piece of 420 nylon fabric as a rollable tarp which can be used to cover the top of the dump trailer.
