In your experience, do they focus on price, or is it more relationship-based when making a decision?

Generally, it's not about price; it's relationship-based and availability-based. For instance, a 2,500 horsepower diesel engine might have a 48-week lead time, almost a full year. Suppliers or manufacturers that procure engines and transmissions in advance usually secure the business. As a buyer, I wouldn't want to wait a year for a product. I might wait six to eight weeks. Pre-purchasing engines and transmissions is crucial to winning business. At the end of the day, it's a Caterpillar or Cummins engine, an Allison transmission. I don't manufacture the engines or transmissions; I make the chassis trailer they sit on. The components are not unique in that way.
