Abstract
Oppositely extending telescopic wheel support sleeves with wheel support cradles are attached to open top shoes provided at the outer ends of the sleeves. Each of the cradles has a connector arm for securing the cradles to the shoes so that the sleeves and the cradles cooperate to support the wheels of a towed vehicle. The open top shoes provided at the outer end of each of the sleeves allow the end of the connector arm nearest to the shoe to enter the shoe by swinging downwardly in an arc extending from a position above the shoe into the shoe. The connector arms are locked in the shoe.
