You will like 24. It is a good road. Major truck stops at the I 65, I 69, and I 57 interchanges. Other locations as well, but these are BIG FUEL STOPS.
This is by far the best and the cheapest way to travel Indiana. Good food at the I 57 truck stop in Gilman, Ill. NE corner of the intersection before you make the right turn to cross I 57. The servings are FAR BIGGER than most RV owners need or can eat and drive again. Good place to sleep in your RV. Very safe area and a lot of room. Parents are buried here and we have traveled this route from Lima, Ohio to Gilman, Ill. many times.
