FYI, I make that drive a lot to go to my offices in St Louis. It's 285 miles from Naperville and the track site MapQuested out at 315 miles. I would allow more like 5 hours, especially pulling a trailer, unless you a not worried about the po-po. It's hard to make good time around the St Louis area. The traffic flow is whacked.
