If you live near a EZ-Pass service center go to it and they will help you out just musure your cab heigth to ground as this will make a differance in you toll sub-class under 7.5 feet is low over 7.5 feet is high class. also most exits you will have to go to a manned botth so they can add the trailerto the toll. This is just a NYST thing they are changing this.You will get a discount of 10% on the tolls. My truck is a Class 2high add a 2 axle trailer from exit 33 to exit 50= $26.00 plus on way. used to be 17.55. Motorhomes pay if they were a car. Hope this helps you out.
