  • Patent number: 7237803
    Abstract: A drag wheel and mount attachable to the angular skid bracket engaged on the rear of a motor vehicle such as a trailer or motorhome without removing or otherwise altering the angular skid bracket. The device features a roller rotationally engaged on the distal end of a mount. The mount is adapted to attach to the angular skid bracket in a compressible engagement without altering or drilling the skid bracket or detaching it from the vehicle. The roller projects past the lower surface of the angular skid bracket on two sidewalls and contacts the road surface in the event the vehicle tilts sufficiently to cause the skid bracket to strike the road.
