I have friends who team there. They like it there. A hiccup here and there but overall very happy. Making quite a bit of coin. That's probably why they are happy! Been there 4 or 5 years.
Worked there for a few years, only left for a change of direction in life. If I were to ever go back driving it would only be with SPD. You can see a lot of what I did there in the Flatbed forums, pictures of loads, paychecks etc.
Are they perfect? Absolutely not however I know of no perfect company. What is my perfect company you may hate however it was and continues to be my experience that they go a few steps extra on many things important to drivers.
