Poolguy,
It depends on the company. Usually, the larger expediting companies require a cdl class c with haz endorsement even in a cargo van. What year is the van? Most companies are looking for 2000 or newer. However, check around again. Some smaller companies will accept older models. Heads up on the liability insurance out of NY. They require that type of insurance to be based out of the state.
Also, it depends what you mean by the off season. Do you mean 3 months or 6 months?
Good Luck,
ABC
