Called ahead just to be sure and they said yes, overnight allowed...semis there all the time. It was not quiet at all. We ended up driving to find something else.

Ok for one night...park over by the Wal-Mart sign

This site shows no overnight parking but We called ahead and they said it was fine to stay. We are in a class A with a tow. We parked out by the Walmart sign along the curb. Nice and quiet place. I would highly recommend. Long live Dylan.
