My Mountain Aire still looks like new and has had only minor problems. It is always stored indoors when not in use and that really helps. I checked my tires yesterday because we are planning a 4000 Mile trip in July. Even the 5 year old tires do not have any cracking on the sidewalls. They only have 20K on the tread. Tomorrow the anti-freeze gets changed. It already has synthetic trans. fluid, and the brakes will be flushed also tomorrow. Imhope to keepit another 10 years, assuming we are healthy enough to keep going.
