The complex trailer can be coupled to a vehicle having a drawing rack and mainly comprises a first trailer and a second trailer, in which the first trailer includes a deck, a bogie wheel, and a landing; the second trailer includes a wagon bed, and a trailing wheel. The complex trailer also has three coupling devices for respectively coupling the drawing rack and the first trailer, and the first trailer and the second trailer. Moreover, the trailing wheels can take the place of the landing wheels and the wagon bed can be combined with and thereby carried by the first trailer in case the first trailer and the second trailer are combined together so as to save space and to provide stable travel.
