So, I will say this for Dometic, they seem to be rather well-practiced at handling the return and refund of their products. A brief call to the recall number listed in the pdf, and my CFX3 75DZ is now waiting on the front porch to be picked up by the UPS man tomorrow. I would encourage anyone that bought a unit involved in this recall to get it returned to Dometic and let them properly correct this issue on new production. I suspect this will be corrected long term, but I don't have a clear indication from them about their future plan. Production is in China, and I doubt they would have stopped production if the long term fix was just to add a sticker. I just didn't want to get stuck with one of the initial lemon units. I was lucky in that the other things on my 12v bus were tolerant of the high voltage back feed.
I will keep update here when I have the refund check in hand.
