Fleet managers operating cylinder delivery trucks, dump trucks, boom cranes, box trucks, snow plows, spreaders, and propane bobtail delivery vehicles can significantly lower their operating costs, carbon footprint, and imported oil dependence with the new Rosh CleanTech Ford F-650, said Todd Mouw, vice president of sales and marketing for Roush CleanTech. While there are upgrade expenses for converting powertrains over to propane autogas, many fleets are now adopting these alternative fuel vehicles.
