Abstract: A trailer includes a trailer frame having a hitch. A stationary support base is joined to the trailer frame. Two supports are slidably guided on the support base toward and away from each other. A wheel assembly is mounted to an end of each of the supports remote from the other support such that a distance between the wheel assemblies varies with movement of the supports on the support base. A locking device selectively locks each support to the support base in a first position where the wheel assemblies are furthest from each other and a second position where the wheel assemblies are closer to each other.

Abstract: A trailer includes a trailer frame having a hitch. A stationary support base is joined to the trailer frame. Two support plates are slidably guided on the support base toward and away from each other. A pair of wheel assemblies is provided, wherein a wheel assembly is mounted to an end of each of the support plates remote from the other support plate such that a distance between the wheel assemblies varies with movement of the support plates on the support base. A pair of drive links is provided wherein a drive link is joined to each of the support plates. A drive mechanism is joined to the drive links and configured to selectively move the support plates toward or away from each other.

Abstract: A trailer includes at least a plurality of fabric support connections that retain a plurality of fabrics spaced apart from one another so as, if desired, to insulate the roof and side walls of the trailer. In one embodiment, the plurality of fabric support connections are connected by way of extrusions to some of the sides of the trailer and further provide insulation by forming a double wall on those sides. In another embodiment, the plurality of fabric support connections form a double wall only on certain portions of the top side of the trailer.
