Apparently the rest of the world purchased these right when they cameouut, in 2010. Well I spoke with Jayco and when your 2010 mega slide motors begin to give u troublle, the more beefy mot9rs they install are stock on the 2011 model which was the last yr they made them. But I am thoroughly impressed with mine. Im a pipeliner and I live out of it. If it can and will go wrong, I promise, ill find it.
