Always make sure that Camco Wheel Chocks are used on the wheels of the trailer to keep it from any movement. The last thing anyone wants it the trailer rolling away when hitching or un-hitching it from the tow vehicle. These Camco Wheel Chocks are made of durable hard plastic with UV inhibitors to protect it. This also allows for easy cleanup if there is mud or dirt on them after use.
It is recommend having at least two, one on each side of the wheels to keep the trailer from rolling either direction.
