Welcome Bdfone
Sorry to hear that you're having issues with your trailer.
Dutchmen & Keystone are owned by the same parent company - Thor Industries. Did you purchase your trailer from a
dealer who also sells Keystone?... simply wondering how Keystone got involved with your (Kodiak) situation?
That said - some members here have also found ripples/delam issues after winter storage [with no apparent water intrusion].
I don't recall whether or not it was determined to be "faulty" glue (as you stated) though. If I remember correctly,
some had used an RV cover during storage, and wondered if that (& excessive heat) may have been a contributing factor.
You might try doing a forum search to find those threads & hopefully others will chime-in soon.
