I-PASS E-ZPASS
How do you use a windshield mounted I-pass or ezpass with a truck camper overhanging your windshield?

We have the same basic thing in WA called the Good-2-Go pass. Mine is right under the mirror and works fine with TC.
I'm an electrical engineer, in the communications field. Remember, these are RF Transponders, not a line-of-sight infrared device. Granted, a camper bunk is a sizable thing, but it is not metal, like a crane boom and support rigging. Your bunk does very little to block actual RF. RF signal from the triggering system for the most part will blast right through it. Even a full 100% aluminum framed camper doesn't block signal much because the ribs are spaced so far apart.
Now, if you had an old-school aluminum skinned camper, that'd be a completely different story.
Here in WA, we are also given "blockers" to prevent them from working when we're legitimately carpooling. Those are 100% metal and prevent the transponder ID from echoing back properly.
