I run an e250 cargo van?I am looking for work and it seems to me that the type of work that will make money for me is emergency deliverys. I run now for an expedited company ; but loads arew few and far between. What is the deal with 10,000 gvw? Why is that weight significant compared to say 12,000 gvw. I see this used often and do not understand what happens when you get to 10,001lbs! Thank you starbryte
