I am thinking of getting an ezpass. Any issues with truck camper overhang. Did you mount yours near the top of windshield as per the instructions or near the botton for less interference from overhang...
I don't think you will have a problem. I've had one in my glove compartment in my toad and it registered. I sent an extra one back and I did not wrap it in foil and I was charged a toll when the mail truck went through the toll booth.
