The impact of vehicle age on service activity volumes indicates both the cyclical nature of maintenance and repair needs for different VMRS Systems and how operating older equipment affects commercial asset service. Changes in these quarterly rankings can also be seen as a reflection of the growing number of new trucks being placed in service and the impact of freight hauling activity on mileage. Additionally, the data shows how routine maintenance and seasonal service needs impact volume. In Q2 2024, Powerplant service continued to rank highest in volume across all four age brackets.
