Trailer truck

I said to make my children a toy, in fact I want to make them many more, but I have to start somewhere. That's how I made this model. It is relatively simple and durable. It also has parts that move just like a real platform. I intend to make a whole collection of machinery.for instruction please follow youtube link:https://www.youtube.com/watch?v=Q-PSRCuhojg&t=5s
