Floor buckled 2018 320S Boondock

This forum has provided us with much support and valuable tips in the past 5 years. I thought I would share our current issue and maybe help out someone in future.
Our 2018 320S Boondock floor has buckled. I would describe it more as a heaving beneath the laminate, resulting in a wavy floor. There is a long bump inside the trailer and another inside the storage area.
We are the original owners, lightly used trailer because Canadian summer is short. Manufacture date is 12/1/17, so likely the Green Core floor was used as a substitute for the Azdel.
We have contacted our dealer today. It is a little nerve wracking, we love the T@B, care for it better than our house! But it is now 5 years old and I don't know what to expect in terms of warrantee service. I will provide an update as things progress.
