It is described in Trailer Life magazine and on the internet. Entregra motor homes, Lance, Coachman, higher end Forest River products, and other manufacturers are beginning to use it as a superior product. I was speaking to The RV Factory regarding their Luxe fifth wheels. They reported that they will be going to this product in the future. In the technical article in Trailer Life magazine they say we will see an infusion of contemporary building products into RV's. Azdel was singled out as a better product that is impervious to water, rot, and delamination. In this owners forum look at all of the people experiencing delamination. One owner of a Landmark was experiencing delamination and his RV was only weeks old. It is time for the RV industry and Heartland have better quality control and stop using products e.g., luan that soaks up water like a sponge when there are better options. I was happy to see that some manufacturers are beginning to take PDI inspections seriously before sending them to the dealers. Supposedly, Heartland is following suite.
