First of all, imagine hitting the highway and finding this monster next to you. Frightening, right?

Wal-Mart Canada is aiming to redefine shipping with the introduction of the Supercube trailer. At 60.5-feet, the two-level cargo carrier is optimized for maximum hauling space. Behind the cab, the drome box adds even more space for goods. This is hauling at new levels, conceived by Ontario-based Innovative Trailer Design. The trucks are only in testing phase, however if they hit the highways fully the vehicles will redefine efficient transport and lesson Wal-Mart's overall environmental impact.
