Find a fiberglass sided aluminum framed trailer that uses Azdel as the backing for the fiberglass. Zero delamination.

Not even close to the truth. Most only use Azdel for the outer substrate layer between the filon skin and center frame and foam layer. The inside is still Luan plywood. Sure the Azdel will not delaminate itself when wet like Luan but the adhesives are low VOC water based. Get water in the panel and the filon can delaminate from the Azdel, or the Azdel from the foam and aluminum tube center, or the inner wall panel can delaminate or fall apart.

Zero chance of delamination is far from a fact. Better yes....Bulletproof? Far from it.

A lot of marketing mumbo jumbo for sure and if it sways your purchase decision so be it.

A thing most people do not consider is the method of lamination. Vacuum bonded panels are far better than panels laminated by pinch rolling. Our 2013 Keystone had no delamination but after 3 years you could see every panel joint in the lamination, because Keystone uses pinch rolling. Were in our 3rd season in our 17 Rockwood and I can not see a seam as Rockwood vacuum bonds the panels.

Looked it up. RV Azdel walls have no wood. they are constructed as follows. Fiberglass exterior, Azdel, insulation, Azdel, décor interior. NONE of the pictures showed any wood period. No wood was mentioned in any of the descriptions. In truth. It was specifically noted that there is no wood, luan or other wise in a Azdel wall. You may know what you are talking about. But the construction cut aways, and specs tell a different story.

It was also NOT promised there could be no delamination, But that the chance is drastically reduced. I tried to download a picture, but it wouldn't. However. you can go to www.azdelonboard.com to see the construction of Azdell. This is the wall construction of the Coachmen RVs.
