The invention relates to a freight trailer (10) which includes a wheeled chassis (12) carrying a first loading deck (14) and a frame (16) carrying a second loading deck (18). The frame (16) and chassis (12) are movable with respect to one another between a first, haulage configuration and a second, towing configuration in which the frame (16) and chassis (12) are moved apart so as to receive a load on the second loading deck (16). The trailer (10) may include two towage connections, the first towage connection (38) being arranged to connect the trailer (10) to a first vehicle and the second towage connection (40.1, 40.2) being arranged to connect the trailer (10) to a second vehicle. The first towage connection (38) may be in the form of a fifth wheel coupling. The second towage connection (40.1, 40.2) may be in the form of a hitching arrangement having complementary shaped hitching formations which are engageable with one another to connect the trailers (10) to one another when engaged.
