A folding trailer may be selectively moved between an extended or use position and a collapsed or storage position. The folding trailer may include an axle that is capable of being moved between a first position in which the axle is generally aligned along an axis and a second position in which the axle is disposed in a folded configuration. The axle is preferably located in generally the same plane in the first and second positions. In addition, the axle preferably moves in a generally rearward direction when the axle is moved from the first to the second position. The trailer may also include a bed that is capable of being moved between a first position in which first and second portions of the bed are generally aligned with a first plane and a second position in which the first and second portions of the bed are disposed in a folded position and generally aligned with a second plane. The axle and bed are preferably disposed in the first positions when the trailer is in the use position. The axle and bed are preferably disposed in the second positions when the trailer is in the storage position.
