There is an exit that has about 3 truck stops, T/A, Petro, and another. It is just over the Maryland/Delaware border, I believe exit 109. You can hit both.

FYI, the next rest stop in MD has a pretty good "Maryland Shop". If you like hot sauces, spices, seasonings, it is a pretty good place. That rest area also has a Starbucks, the only good coffee between NJ and Baltimore.
