Abstract: A trailer adapted to be pulled by an automobile or other vehicle and adapted to support a boat is also used to support at least one motorcycle. The trailer has a longitudinally extending horizontally elongated bar. First and second parallel vertical plates are secured to the bar and extend upward and outward therefrom at right angles thereto. A horizontally elongated member pivotally engaging the bar is disposed between the plates and extends outward therefrom at right angles to the bar. Means are provided to lock the member in horizontal position or to release the member and allow it to pivot. In use, the member is allowed to pivot until one end touches the ground. A motorcycle is then rolled on top of the member until it pivots back into horizontal position. The member is then locked in place and the motorcycle secured in position on the trailer. Alternatively, an extension can be detachably secured to the member to enable the motorcycle to be moved into position.
