I've worked on a few vettes over the years ( look on some of my older posts and profile) and have only seen cracks like this from stress (collision or floor jack) old fiberglass-like 30-40 years old will sometimes have some strand seperation and Uv age damage.
OP I would suggest you take your mh to a RV collision repair center. A nornal dealer doesn't have experiance or knowledge about how to handle stess cracks, frame flex or any kind of real body repair. This sort of damage requires a whole different perspective and knowledge of vehiclular geometry that very few individuals understand or can fixure out a corrective repair plan.
Sorry about your troubles.

Agreed aged fiberglass is normally where one would see this. I toured the factory and FR makes their own wall panels and slides. If something went wrong with the curing process you might have a problem with these but since the door also has issues, which is a vendor supplied piece, I still think the problem is environmental related. Since the cracks are more prevalent on the darker paint which gets heated by the sun more it also points to an environmental issue. I don't think it is a chassis twist or flex related since it is not on both sides and the slide and door would not likely be effected.
You are correct that lasting repairs for this kind of issue takes special experience and knowledge after the root cause has been determined and remedied.
This got me to check my 2012 which fortunately does not have any cracks anywhere I could see. It is however stored inside a steel building but for the first few months it was outside. In the morning as the sun came on one side I could hear the coach creaking and crackling as the one side heated up. I could also feel the temp difference not only between the sides but also between the light and dark paint. I assume they put flex agents in the paint like you do on flexible car bumpers to handle the expansion differences.
