  • Patent number: 5069471
    Abstract: A travel and utility trailer combination includes a house trailer with a wheel mounted main frame supporting a main closure or house. The main frame has two spaced-apart side beams rearwardly thereof. An auxiliary trailer is hitched to the main frame to have position between the side beams. Side beam extensions are pivoted to the ends of the side beams to have end portions underlying the axle of the auxiliary trailer. A hydraulic linear motor is provided to raise the side beam extensions to horizontal positions to lift the auxiliary trailer wheels off of the ground for over-the-road travel. Removable positioning pins passing through openings in the side beam extensions and plates integral with the side beams maintain these extensions in horizontal position.
