I don't know if this is the correct forum, but customer service is not responding. My question is this. Do I need a separate transponder just for my fifth wheel?
Interesting. I picked up my EZ Pass transponder several years ago in Indiana (called I-Pass there), and have only ever had the one which goes with us in either the car or truck, whether towing or not. We've used it in just about every state in the east, northeast, and central U.S. and have never had a problem. Maybe ignorance is indeed, bliss. ??
