A tongue member has a rear portion connected to and forwardly extending from the frame and a forward portion adapted for releasable connection to a trailer hitch of a tow vehicle. A tongue extension includes two extension members pivotally connected together to a central connecting member and pivotally connected at a corresponding opposite end of each extension member between the forward and rear portions. The extension members are pivotally movable between the upright side-by-side stored position and the deployed position in end-to-end fashion and longitudinally aligned with the forward and rear portions wherein the effective length of the tongue member is extended by an amount equal to the combined length of the extension members.
