To answer the question in the title ( since I forgot the clip where I talk about the differences )

I like hauling grain in a dump trailer because when you pull over the pit, you only have to line up to it once. With a set of trains it's usually 4 times and that's if you stop at the right time.

I like hauling with the trains because you can fit 4 or more extra KG in the box because of the extra axle and the way it's set up! But they are long , wiggly and for most, pretty hard to back up.

For what I think is better.. I would say a well set up dump trailer with more then 4 axles, a big door in the front so it's easy to get in and clean if you are switching product ... plus then you can run a stretched out truck!

Thanks for watching everyone!
