From Halopedia, the Halo wiki
The Dewmax is a robust high-occupancy transit vehicle manufactured by the vehicle manufacturing company, Kabord, which was originally based out of Vallejo on the Inner Colony of Ballast. The Dewmax has earned favor from a wide variety of clientele, and can be found in a diverse collection of settings – from corporate fleet lots to down by the river.
The Dewmax is a static prop on a number of Arena and Warzone maps in Halo 5: Guardians. As well, the Dewmax is a placeable Forge object in two forms; the normal version and the mural version from the Warzone map Urban.
