Abstract
An apparatus and system are disclosed for an expandable trailer. The apparatus, in one embodiment, is an expandable trailer that lengthens from a compact position to one of a plurality of extended positions. The trailer may comprise an axle assembly to mount a plurality of wheels, a frame having a front and a back, and an extension mechanism configured to lengthen the frame from a compact position to one of a plurality of extended positions, such that the front extends a front distance from the axle assembly and the back extends a rear distance from the axle assembly. The extension mechanism further maintains a proportionally greater front distance than the rear distance. As a result, the expandable trailer provides a properly distributed load-bearing area, with respect to the axle assembly, in the compact position as well as the various extended positions.
