I have a run going into Kentucky tomorrow evening and after looking at mapquest it recommends using the Hal Rogers Parkway. Is this a truck restricted road?
Still not certain where it is... but KY is trucker friendly...not aware of any highway restricted to commercial traffic with the exception of weight restrictions... don't think that would be a problem for your cube van.
I assume you are aware of the need for a Visa for those living in the Baltimore area?
