I will tell you one more thing. If you are worried about break downs in your coach, you are not driving it often enough. It is a fear of the unknown. If you drove your coach once a week, you would have no fear.
I say this because I'm about to embark on a vacation and my coach has sat idle for longer than it has ever sat in the 12 years of ownership - 4 months. I'm more paranoid as a result, because of the unknown. I took it out last night, drove it to get fuel and shake it out a bit. Everything was good, although my rear axles seemed to be warm. I'm a little less paranoid after driving it. I still have to check out the rear axles, it may be just rust on the rear brake rotors. I'll jack them up and make sure everything turns free before we go. Other than give it a serious bath, I'm good to go.
