Claim:
A trailer comprising: (a) a frame extending along a longitudinal axis, the frame having two sides, a front end and a rear end; (b) a steering linkage coupled to the frame; (c) a pair of front wheel assemblies coupled to the front end of the frame and a pair of rear wheel assemblies coupled to the rear end of the frame, wherein each of the wheel assemblies is spaced laterally outwardly from one of the sides of the frame, and each of the wheel assemblies comprises: (i) a wheel carrier comprising a pivot member pivotally coupled to the frame along a steering axis, the wheel carrier being coupled to the steering linkage so that actuation of the steering linkage pivots the wheel carrier about the steering axis; and (ii) a wheel rotatably coupled to the wheel carrier along a wheel axis, the wheel axis being oriented approximately perpendicular to the steering axis, wherein the wheel axis is offset from the steering axis; (d) wherein the steering coupled to each of the wheel assemblies such that when the wheels are oriented along the longitudinal axis, the wheel axis of each of the front wheel assemblies is offset from the steering axis in a forward direction relative to the steering axis, and the wheel as of each of the rear wheel assemblies is offset from the steering axis in a backward direction relative to the steering axis.
