The present invention is directed to a trailer comprising a platform supported by a hitch assembly and at least one wheel assembly. The hitch assembly is for rigid attachment to a vehicle. A vertical guide mechanism connects the platform to the hitch assembly. The vertical guide mechanism includes a first vertical guide element capable of moving parallel to a second vertical guide element. The first vertical guide element is mounted to the platform and the second vertical guide element is mounted to the hitch assembly. A lifting mechanism is integrated with the vertical guide mechanism for raising and lowering the platform. When the platform is raised and lowered to the ground, the platform remains substantially parallel with the ground.
