Our Jayco had a wall that delaminated. It was apparently due to improper layup at the factory. Jayco covered replacing the entire curbside wall at our local dealer. It looks fine now.
I am so glad for the 2 year warranty since the problem did not show up until partway through our second year of ownership.
