Qualifications to operate a cargo van are pretty basic for most of the expediting companies out there. All you need is a cdl c w haz and a fairly clean mvr with a current d.o.t physical. Of course passing a drug test a no recent felonies usually helps also. Whether your looking to bring your own van into a system or drive for a fleet owner, usually companies are looking for a 99 or 2000 or newer 1 ton or 3/4 ton van with at least 9' of cargo space. However, keep in mind if you are looking to drive for a fleet owner, they may require you to stay out a certain amount of time.
Hope this helps,
