The Crestline Hauler-Rig is a heavy-duty exo-assisted ground vehicle built around a modular cargo spine and six independently articulated drive wheels, each capable of torque-vectoring across uneven terrain. Its onboard load-balancing AI — called the Ballast Cognition Module — continuously redistributes weight across the chassis to prevent tipping on collapsed infrastructure, rubble fields, and the deeply rutted access roads that connect GLMZ's outer districts to its central arcology cores. Power is drawn from a dual-cell hydrogen compression stack buried beneath the operator cab, giving the Crestline a range of approximately 900 kilometers before refuel under full load.
