I had 2 Trailers with similiar bubbles. Both trailers had to have the complete wall replaced they were on. I would find out from dealer how they are going to fix. Not sure it is something that can be fixed correctly without wall replacement. Bubbles/Delamination has been a problem with many trailers including new ones. Something to definitely watch out for and get fixed as soon as possible.
For Newbies getting into camping, this is something I would look for first as its a major expense to get fixed if not under warranty.
