The innovation came about after having seen many campers with trailers having enormous difficulty parking their trailers with their vehicules. Hence, I came up with an easy way to handle trailers or boats without continually backing up and going forward with their vehicles. The invention is an electric wheel which attaches to the trailer, giving the trailer a front wheel or fifth wheel. The wheel has a motor, a battery (either attached to the wheel or borrowed from the camper trailer), and has a handle. This enables a trailer owner to place the trailer anywhere he wants with little effort. It's concept works like a child that pushes and pulls a wagon.
