Semi trailer float for the digger.
Using 9397 and 9395 I have built a truck and trailer for carrying the technic digger. The truck is now a V8. To access the engine you tilt the bullbar down then tilt the engine cover. The fifth wheel pivots and rotates like a real truck. The log grab is converted into a Hiab type crane with a winch drum on it. The trailer wheels are a bogie system that allows all wheels to stay on the ground with undulating terrain.
