The chassis determines the truck's wheelbase, fuel tank capacity, and axle configuration (e.g., 4x2, 6x2, 6x4). A longer wheelbase generally provides more stability but reduces maneuverability. 6x4 chassis are ideal for heavy loads due to increased traction. Cabin types range from day cabs (no sleeper) to large sleeper cabs. Sleeper cabs allow you to rest anywhere, while day cabs are lighter and cheaper. Choose a cabin based on whether you plan long hauls or local deliveries.
