2016?Thor Hurricane .. back camera has started intermittently going off, loss of signal on screen.. after a few minutes .. it reappears ... when on.. most times many jumping lines .. other time very clear and stable .
I’ve rearranged some wires under dash... no change , and wiggled back camera ... no change ?
I had same intermittent rear camera problem on 2018 Thor Vegas. Gained access to rear camera wiring behind panel in rear of coach inside a cabinet. Found wires from camera connection to cable running to front of coach "half assed" twisted together and wrapped with electrical tape. Was shocked at the piss poor workmanship. Repaired with typical electrical wiring crimp connectors. Problem solved.
