Depending on the type of job there is a fair chance if you want a trucking job in Florida you should look locally. Generally if you look at a locally based trucking company you may get home more often if you are an otr truck driver. However if you are not a truck driver then a trucking company with a facility in Florida makes sense.
Trucking jobs in the United States will always be available. Driver jobs of big rigs can never go away as it is not possible. That is one good thing as it does not seem possible to relocate truck driving jobs to some other place. That does not mean jobs can not be lost due to a slow economy. They can if not as many people are buying products that need to be shipped. The turn over of drivers may be high in good times and may or may not be as high in poor times.
