Class B--OTR available?

Hi, I know most of the drivers on here are Class A, but I was wondering if anybody has info on the Class B tankers (hydrovacs, I think) that travel with test drilling companies or anything similar?

Would also be interested in a similar company willing to hire on a Class B for that & require them to train up to a Class A within a limited time frame.

Thanks!

 

Thanks, I'll be looking into 'hot shot' companies; I know a Class A driver looking for work right now, too, so that might be just perfect. I guess it never clicked that some of those would be Class B--haven't seen any of them that size in this area.
