suggestions on overnight camping along the way?

From Newark, it's a good part of the day to the Columbus Ohio area, perhaps a bit farther. I'm only about 15 miles east of you, and when we went west in the summer of 2012, a construction-based traffic tie up took almost two hours out of the day, but it was still nightfall by the time we reached Columbus. I agree with the others re: 95, 695, 70, 68, 79 up into PA, and then 70W - the only toll on that whole journey was the JFK Highway in Delaware, which I'm sure you know about. 695 can be a little slow until you get past Towson, but after that it's smooth sailing. We ended up staying at a Pilot/Flying J in, I think, London Ohio that first night. It was about 560 miles in one fairly long day.
