Best tanker companies in NC to work for?

I've never worked for them, but there are two companies in the Raleigh area named Puryear... one runs dump trucks (they're the largest dump truck contractor probably in the whole state), end dumps, and I think they have some RGNs.. they support the construction industry. Basically, if you work for a decent construction company and get pissed off with your boss, they're the company you go to for the next few months until you come back begging for your previous job back. They used to do the brokerage for CC Mangum (now known as Fred Smith Company) jobs, at least in the RDU area.
The tanker company is related... I've heard a couple different stories... one is an offshoot of the other, two brothers started each company.. don't know which is true, if either. But their affiliations with the other Puryear is enough to make me wary of them, personally. But, for all I know, they could be a great company. I really don't know, but I guess you can always call and talk to them. Do a Google search, since I can't post a phone number on here.
