Span: Enter the distance from the center of the 5th wheel to the center of the rear axle group. Note a positive number indicates the 5th wheel is "ahead of center," a zero indicates "on center" and a negative number indicates "rear of center." 5th Wheel to Axle Group Centerline: Axles Number of Front Axles on Truck: 1 Number of Rear Axles on Truck: Jeep Data Enter Jeep Dolly information if it applies. If not, all entries must be set to zero. Axles Number of Axles in Jeep: Empty Weight Kingpin: Jeep Axles: Total: Dimensions Enter the distance (Span) from the Jeep Dolly kingpin to the center of the Jeep Dolly’s rear axle group. If Jeep Span = 0 then no jeep.
