Thank you for the replies so far. Let me clarify my question. I am not asking what the maximum loaded capacity of the bus is, which is the GVWR (Gross Vehicle Weight Rating), but I am looking for the empty weight with no people on it. The GVWR is found on the VIN label on the bus. I have seen a label for this model bus and the GVWR is 36,900 pounds. That is the MAXIMUM loaded weight. Therefore, the empty weight cannot be 40,000 pounds. The empty weight of a vehicle is not listed on the VIN label.
