If you have a short bed truck, I would think using a non-storage wrapped camper made for a long bed using the truck’s taillights and the same weight center of gravity as the short bed model would work with this caveat:
How wide is the lens image in the tail light? If it cannot operate correctly with the center blind spot with the camper on, this would cancel your ability to use the sensor.
