Difficult to know exactly the extent of spider cracking your referring to. Is it near the edge(s) or stress points? A point of impact? We once had a bird hit a front end cap at 60+ mph that left a grapefruit sized mild spider web. The cracks were not very deep. Frequent waxing made them less visible. Similar to boats gel coat cracks are usually a result of impact or stress to the fiberglass.
Our current coach arrived after transport with an apparent quarter sized stone chip. We're having it repaired at the factory facility with a few other items.
Generally, I'd not expect to see any on a "new" coach, or expect quality warranty repair or financial compensation.
