Ez pass locations

Best two placements I found on my Monaco was about 3-4 inches off the dash center window, but the dogs kept knocking it off when parked. I moved it to about 3' off the dash and it worked just as well. when I placed it very high on the windshield it would not hit most times.

I thought of it this way, the reciever is aimed to pick up a passanger car or truck with the tag mounted behind the rear view mirror. So lower on the windsheild is closer to the proper aiming then higher up due to the height of the vehicle.
