Abstract
Abstract Combination house and auxiliary trailer apparatus including a frame carried on a pair of wheels and having a main closure mounted thereon. A pair of spaced apart tracks project rearwardly from the main closure and an extendible closure is carried thereon for telescopical receipt in such main closure. An auxiliary trailer is provided with a rear portion that is receivable between such tracks and includes a pair of support wheels and retraction means for retracting such support wheels to an elevated position. Coupling means is provided for coupling the auxiliary trailer to the rear portion of the house trailer whereby the extendible closure may be moved to its retracted position in the main closure and the auxiliary trailer moved into position with its rear portion extending between the tracks. The auxiliary trailer may then be coupled to the house trailer and its support wheels elevated to enable the combination to be towed as a unit from the tongue of the house trailer. When the destination is reached, the retractable wheels may be lowered and the auxiliary trailer uncoupled from the house trailer to thereby free such auxiliary trailer for use independent of the house trailer and enable the extendible closure to be moved rearwardly on the tracks to cooperate with the main closure in providing a composite closed area.
