ATF: North Trail - NorthTrail 23 Roof Bubbles

We picked up our North Trail 23 in May. It was a 2014 but it was new and is under full warranty. In June we installed a vent cover and took that opportunity to inspect the roof thoroughly (as the dealer suggested) and touched up a little bit of caulking - all was well. Last month I went back up to to inspect and found numerous mid sized bubbles had appeared, in numerous places but predominantly at the leading and trailing edges (front and rear). I am assuming this may be where the greatest lift is caused by the airflow over the trailer. We took the trailer back to the dealer who says the bubbles are normal and nothing to worry about. I have difficultly with that; particularly because the bubbles are right at the edges and are therefore causing the caulk to flex dramatically. This will eventually cause the caulk seam to break and leak.

Here's a few pictures:

Any assistance would be appreciated

That was a problem before you bought it.don't let anyone tell you it wasn't because they are lying
