In Florida, the largest supermarket chain Publix uses its own trucks. Wal-Mart uses its own trucking company to supply stores here.
The problem with Florida is, it’s a big “in-coming” state and small “out-going” state. In other words, we need more trucks coming in to deliver than we need trucks to transport out of the state. There are more trucks that deadhead after they deliver within Florida. Being a shipping manager in the materials handling company, I understand what a problem with a shortage of trucks can be like.
