I must admit, my wagon is rather interesting. First of all, it has a goose neck hitch! I put one on just to see if I could do it and because, well, it would make my trailer unique. It is really unnecessary, but I like it anyway. Second, the hinge is at the back, (like a dump truck) and the way I built the trailer (completely from "scratch") makes it pretty much impossible to put the hinge in the center. The wagon is pretty big. In fact, it has two axles (wheels from a golf cart and from a regular garden trailer) which makes it look hilarious. But I don't care......
