Sadly the answer to your question is "Yes"  They are either structural or cosmetic and sans a hands on inspection I can't tell.

I would suggest a good RV or Boat body man take a look at it,,, Perhaps a friend who works on the six=pack plan if you can.

I have some "Stress cracks" in my almost new rig, however these are not structural, they are in the paint only and in an area where I don't give a you know what.  So I'm not worried about them,, Just keep them sealed with wax

Yours, I can't see, I can't feel and I can't tell  Sorry. 

Cracks in the finish on any large somewhat flexable panel do happen.  But the question is are they serious

Before my last 2 coaches, I've owned a couple of older RV's, a 1989 class C and a 1979 class A.  I've never had a problem with cracks in the fiberglass to the extent you are depicting and, although I'm not an expert, I believe the cracking you are describing is potentially a significant problem.  I agree... have it checked professionally and avoid a possible $$$$$ mistake.
