2003 Four Winds 5000 - Advice

I had a similar model and it performed very well. As per previous responses, the general items are engine and drive train, tires and roof. Also pay particular attention to the fiberglass sidewalls. The window seals are caulked, and if not maintained will leak. Look closely at all angles and lift to make sure there isn't any delaminating. One issue we experienced that I thought was strange was the AC gasket began leak allowing condensate water to drip into the interior through the supply duct. This is easily identified if you run the rooftop AC until you can determine that the condensate drains off the roof.
