I would send your RV dealership a detailed e-mail identifying your findings even though the TT is in storage (initiate dated paper trail), and confirm receipt with a phone call. Depending on your RV dealership's initial response, you may at some point need to send Jayco a copy as well.
If upon RV dealership inspection there is a factory assembly defect confirmed (panel not secured as designed, etc.) with the area in question, then it should be corrected immediately under warranty to insure no associated damage takes place.
I had an issue on my 2018 TT (under warranty) where the factory didn't trim off the top edge of the aluminum siding enough in a couple areas, which resulted in the aluminum edging noticeably raising the TPO roofing material above the roofing surface. It was only a matter of time before the sharp aluminum edge would puncture through the TPO.
Jayco approved my RV dealership's submitted warranty service claim to repair the factory defect which involved removing the metal gutter trim, backing the TPO away from subject areas, trimming back the aluminum as required, and reassembly.
