They nickel and dime you to death, that is for sure. And their insurance isn't cheap and their fuel discounts are (or were) terrible. They work the spot market for freight, and when I left they only had maybe 3 or 4 direct customers of their own.
You can make money there, but aside from the dispatchers I can tell you nobody in management has any experience in trucking (they don't consider themselves a trucking company but, rather, a tech company) so you will spend a lot of time fighting with them because they don't have a clue. In short, that is a lot of the reason I decided to leave and return to driving.
