A novel trailer for use in hauling loads behind a motor vehicle is disclosed, where the trailer is of the fold-up type and includes a slidable bed that can extend and retract, at least one winch with cable attached to the slidably bed for operation between a use position and a stored position, a suspension system with wheels and tires for rolling support of the trailer when being towed, a hitch for connecting the trailer to the motor vehicle, and a hinge for cooperation in allowing the rotatable transitioning of the slidable bed. In an alternate version, a trailer includes a primary bed and a secondary bed that are telescopically slidable into a stored position underneath the motor vehicle.
