I bet both of you have water damage UNDER the siding. Filon don't delam for no reason.

I wish it was that easy. There was no sign of any water damage when I took the windows off, on the inside or on the outside. And the luan when I shoved a tiny camera down by the window showed it was separating from the siding, but none of the rotting stuff that water causes. Plus, the entire trailer was caulked and sealed a few months after I got it (windows removed, sealed, etc). The bubbles only expand in the winter. I have a hard time believing water damage with no sign of water damage could have this big effect starting at 6 months and in just 2 years.But, it could be invisible water damage. But, if it can do this with no sign it would have to be a mfr defect.
BTDT myself and wouldn't agree this is necessarily because of water damage. My own 2008 K-Z Spree 240BH-LX which we purchased new began to delaminate on the curb side about 3 years into ownership for no apparent reason. Careful inspection showed absolutely no signs of water leakage anywhere yet the curb side wall would crease outward in several locations, the hotter it was the worse it looked and in cold weather was hardly noticeable at all.
This was on the side that took the full brunt of the summer sun while the trailer was parked here at the house, the street side which was in shade all the time never delaminated at all. My conclusion was the adhesive inside the wall just let go and there was nothing I could do about it as I wasn't going to dump $1000s into repair that may or may not make it look any better. We eventually sold the trailer several years later, not because of the delamination, but because we no longer required a trailer with bunk beds. JMO, but I'd suggest you just enjoy camping with your trailer as it is and not worry about this delaminnation, particularly if you're convinced it's not a water intrusion issue.
Hate to quote a post that take a lot of space, but Soundguys photos CAN BE CONSIDERED COMPLETELY NORMAL FOR FIBERGLASS LAMINATION.
Filon which is a thin fiberglass skin like any other fiberglass product has a completely DIFFERENT expansion/contraction ratio compared to the material it is laminated to.
Result of heating and cooling cycles over time IS areas of bubbles where the expansion/contraction of the bond between the two materials lets go.
Absolutely nothing can prevent this from happening especially on long, long trailer walls.
It IS the "nature of the beast", sometimes the bond holds and sometimes the bond doesn't.. Fiberglass has a large expansion/contraction ratio..
Not worth the hassle or cost of fixing nor is it worth getting an ambulance chaser to file a lawsuit.
USE it as it is, just make sure any new spots that may show up is not caused by a water leak and you are good to go.
Camp and don't sweat it.
