A trailer, comprising a trailer coupler portion, a trailer frame attached to the trailer coupler portion, and at least one caster wheel attached to the trailer frame. The trailer coupler portion comprises a trailer hitch including a proximal hitch portion, a distal hitch portion, a hinge link connecting the proximal hitch portion to the distal hitch portion, and a hitch locking mechanism adapted for locking the distal hitch portion in position with respect to the proximal hitch portion. The caster wheel(s) include a spindle attached to and adapted for swiveling with respect to the trailer frame. The trailer may further include a caster locking system adapted for preventing the spindle from swiveling with respect to the trailer frame. The caster locking system includes a drum attached to the spindle of the caster wheel(s) and further includes a hitch pin lock having a body and a pin. The drum has a pin aperture through which the pin may extend to prevent the spindle from swiveling.
