The side expansion system is available in two versions: full storage configuration and right-side equipment expansion configuration. It increases storage capacity along the trunk side-window area. Both side-window areas are equipped with Molle expansion protective panels, which protect the win- dows while enhancing storage capacity. In certain situations,they also improve trunk security by making items less accessible and reducing theft risk.The right-side equipment expansion version features dedicated mounting positions for ARB twin air compressors, air tanks, EcoFlow power stations, in-vehicle charging systems, and other onboard equipment. This refined and space-efficient layout allows optimal use of otherwise fragmented spaces, significantly increasing overall trunk storage effi- ciency.
