I have a 2015 Four Winds and my converter decided to quit on me half way through our cross country travel. So it does happen but itís also 5 years old now. Luckily I had previously installed aTru Charge II when I installed my solar system, four years ago, and was able to start using that. I only say all this as for once I was ready for something like this to happen given the reputation of the OEM converter. But......it did last for five years. Just happy that I donít have to go out and find a new converter while on the road in the rain and hassle the change out. Once again a happy camper.
