Incorrect. Actually Azdel being a "selling point" is correct, but its the same as "enclosed underbelly" or "artic package". Just selling points and the only benefit is what you believe it to be. They all make for nice colorful stickers on the side of the trailer.
A laminated wall is 4 layers. Fiberglass/Azdel or Luan plywood/expanded Styrofoam/Luan plywood with vinyl wall covering. You also have a minimal aluminum frame. On a Freedom express that aluminum is 1" square tube. I say minimal as they only put an aluminum member where they absolutely have to. Its not like a house with a stud @ 16" or 24" on center. On your trailer they may be 3' apart. Window openings may not have an aluminum frame, especially smaller windows.
Even with "Azdel" you still have Luan for the inner wall surface, and you still have somewhat water soluble adhesives holding the entire thing together. Add water and the glue releases. The fiberglass may pull loose from either the Azdel or luan, or the Azdel or Luan may pull loose from the foam etc. The only difference between Azdel and Luan is that if it does get wet the Luan will absorb water and may possibly delaminate itself. It doesn't matter though once water is in the mix you have problems no matter if the outer substrate is Azdel or Luan. Azdel is only used for the outer substrate layer in the sidewalls. Its not used in the front or rear walls typically. I don't see the benefit of the Azdel. It may not rot, but how is that a benefit when the entire assembly is failing regardless? The roof substrate and ceiling is also plywood. All Azdel amounts to is smoke they blow up prospective buyers rear ends that it's some great benefit.........it's not. Better than luan? Yes a little. If it has any benefit at all it is that the panel seams do not telegraph as much through the fiberglass as luan, but eventually they still show up even with Azdel. It's not the saving grace its claimed to be. Now if they used Azdel for both inner and outer wall layers, both the roof substrate and ceiling panels, and top and bottom layers for the floor along with 100% non water soluble adhesive, and extruded foam which does not pull apart you may have something that's a benefit.
The floor is the same type of construction although there will not be any Azdel . As far as fixing a floor that has received water damage leave that to the factory. Its not as easy as its being made out to be. Even when fixed at the factory its still going to be a "patch job". In order to repair it to its exact condition when made you need to remove all the interior items and the sidewalls. They are not going to do that. The floor and floor covering is done before everything else.
The trick is not letting water into the laminated assemblies to begin with which is why all the manufacturers stress the importance of regular sealant inspections.
I also have to ask, why wasn't this bad roof sealant job picked up during the PDI? Its not like it was a hidden defect. By not finding this and pointing it out during the PDI you left yourself open to the finger pointing warranty game. Technically the dealer should of found this during his inspections, especially since its in a place so easily seen. Where was it purchased?
