I work with a bunch of them up in Valdosta, but they're all live bottom guys hauling trash and fluff out of south/central Florida. I'm sure that does you no good, but I know the covered wagons have the newest equipment, most of their live bottom and dump wagons are old and pretty wore out, as well as the trucks pulling them. I don't think you'll find a lot of info on here about them, I asked the same question a month or so ago and got no responses, good luck..
I called the Florida office and they aren't looking where I am but told me that Oxford might be looking for OTR guys, missed them on Friday so I'll be calling on Monday, I'll let you know what they say. I know around here they do Walking floor and dump.
