What the service mix says
A store carrying mining fleet services, mobile service and oil changes in one list is covering the full width of Purcell's business from one address. That is a Phoenix-shaped answer: a metropolitan area with mining and construction around it, freight running through it, and several million people who drive cars.
For a business with mixed equipment, the practical value is that the haul truck, the service pickup and the owner's car are all handled in one account at one place.
