Cabinets and Trim on 2021 356RLT failed Winter in Pacific NW

Been RV'ing for 20 years, owned every type of RV except for class B.  I don't live in a super cold environment but we on rare occasion drop to the 30's or upper 20's.  During the winter we always just winterize and wait until February to repack and go again.  Well, this was our first get ready to pack and go... I open up the 5th wheel (we got to use only about 5 times all last year as we bought this one late in the season), and my eyes promptly drew onto popped seams on the island kitchen, ceiling trim, most of the kitchen overhead doors glue joints expanded, doors on the cabinets were overlapping and didn't close.  Such a wreck!!!  We had some snow but these 5th wheels are 4 season rated.  If it happened to this trailer, what happened to others on lots or other customers?  

I've attached 4 pics. 
I would like to find out if you have experienced similar issues.
