About 10 years ago OH raised their rates but also changed the way they calculate which class a vehicle is in. It used to be by weight, but now is on a number of things including height. My 20" Class B camper van was barely under the weight limit before and I paid passenger car fees. Now it's over the 7 1/2' height limit and it's in class 2, much higher fees. I drive from MI to Pittsburgh 3 times a year and figured out a way to avoid most of the OH TP. My route is good, takes about the same time, gets me cheaper gas and better scenery. You should try it. I am figuring out an alternate route going there to avoid the high PA toll for the 1st 28 miles I travel. My OH route follows:
75S to 280S (N Toledo)
To 420S
To East 20
Drive 50.2 miles
To 13/250 SE (SE of Norwalk, OH)
Drive 16.5 miles
To 224E . There’s a traffic light at the 250 & 224 intersection. This is the ‘worst’ of the roads.
Drive 28.7 miles
To 76E
Drive About 61 miles
To Mile 218 Entrance to Ohio Turnpike
