ATF: Landmark - paint cracks

I have a 2012 Landmark Rushmore 5th wheel. When I was waxing the coach I have noticed cracks in the paint. There are 5 cracks in the paint that I have found. What could be causing the cracks, will Heartland repair the cracks? The picture I have sent shows the crack in the paint up close. All of the cracks that I have found are on the non door side of the coach.

I 'm not sure about your paint but on a car, if the hardener in the clear coat cures to fast it can cause this. They should be a simple fix if more don't start to appear. It can be feathered in and reshot with clear coat in that area to blend it all back in.

To me, those look like impact cracks, hail storm maybe??
