I live in NH, bought my EZ Pass in NH and was told my Class B+ Born Free 22 ft MH is a different class from my passenger car. When I went through tolls using it on a trip to Gettysburg, PA, the toll booth registered a higher toll than friends I was caravanning with who were driving a huge Dodge with a truck camper and towing a trailer with a motor cycle. Kind of bummed me out!
But when I got my monthly statement, the actual charge was the same as my passenger car is charged! Go figure! I'm not complaining. Love the ease of the EZ Pass and in several places they have EZ Pass lanes that are at the same speed as the rest of the highway - love those!
