A megatrailer is a special design of a semi-trailer . In contrast to standard semi-trailers, a megatrailer has a clear loading height of 3 meters. The development of the megatrailer goes back to the Dutch logistics company Ewals Cargo Care , which introduced a megatrailer for the first time in 1990 to increase the efficiency of regular delivery traffic between continental Europe and the factories of the automobile manufacturer General Motors Europe in Great Britain . The design of the trailer was based on the dimensions of the transport boxes for supplier parts used by the automotive industry.

A customer had this to say, "Not worth at all. very cheap make and poor quality. Bought it earlier to gift my son and when he opened and start playing with it it was too late to return. well at least I can warn others not to fall in the same mistake."
