The truck won't pay for itself in one season. If you are doing a shopping center you should most likely look into buying a sander as people like to "slip and fall
." 460 is hard on fuel especially plowing, you'll probably be lucky to hit over 5 mpg. If you don't need the truck for the summer time pass on plowing this year, build up some finances and look into it next year. The best advice I learned about plowing, use the best equipment you can afford because no one likes turning wrenches at 3 AM because yor rig broke down.
