Abstract
Abstract A combination house and auxiliary trailer including a house trailer for mounting an enclosure and supported on a pair of wheels and including a forwardly projecting tongue for connection with a towing vehicle. An auxiliary trailer includes a pair of raisable support wheels and elevating means for raising them from a ground engaging position to a ground clearing position and, further, includes a rearwardly projecting tongue for connection with a towing vehicle. Support means is provided for engaging the front extremity of the auxiliary trailer with the rear extremity of the house trailer to support such auxiliary trailer cantileverally therefrom whereby the two trailers may be coupled together and the raisable wheels of the auxiliary trailer raised to their ground clearing position and the trailers towed as a unit. Alternatively, the raisable wheels may be lowered to their ground engaging position and the trailers uncoupled to be towed independently of one another. The enclosure may include an extendable portion which may be selectively extended when the trailers are separated to occupy the space occupied by the auxiliary trailer when the trailers are coupled together to thereby provide an enlarged enclosure for use as living quarters.
