I put this under class A as I believe those driving Motorhomes ( especially longer heavier w/tag axles) would be paying much higher tolls than fifth wheels or travel trailers, and perhaps more likely ...
I admit that it has been several years since I last used the PA turnpike but I was upset because the tolls that I was paying apparently did not go for road maintenance. The highway was filled with potholes and it was not a comfortable ride at all. I did just see an article where the PA turnpike tolls will go up on Jan. 6th.
