Most delamination occurs due to water damage that causes the luan plywood to seperate. As I understand the new Adzal (sp?) are not subject to this because even if subject to water damage it does not have layers that seperate like luan.
Delamination can also occur when defective glue is used.
People like what they have so take what you hear on here with a grain of salt. Go to some campgrounds and talk to the owners. The statement made about 1 in 3 smooth sided trailers delaminating has not been what I have observed and we have visited every state in our RV.
