I have a swivel wheel made by "Toy Tote" and have hauled two Quads all over OR, CA, NV, and AZ. It mounts solid to the back of the 5th so you can backup. Some say it's not legal, but in the 4 years that I've used it I've never been stopped. It's made in Lake Havasu City, AZ. He builds just about any size and shape.
