One of our wiper arms broke when very new. Called Monaco (MCC had since gone bankrupt, so I had no warranty) and they sent me a new one--don't remember the price. No problem with the new one, but of course the other OEM arm broke, too, and was similarly replaced. Fleetwood and Monaco are now owned by the same parent company. I just wanted to let you know that in our case the new arms have been going strong for at least 5 yrs.
