When we had our 1994 Hallmark it had the same problem at the roof edges seam but it had an aluminum roof skin. After calking it a few times, but over time only to have the problem reappear and provide a place for a potential leak.
I scraped and cleaned all of the old caulk/ sealer off and used 3M 5200 marine polyurethane adhesive/sealant to reseal the entire roof edge. Several years later when I sold the camper it still looked great, with no evidence of cracking or separating at all.
Our 2011 Hallmark has the one-piece molded fiberglass composite roof, what an improvement! I know it’s a costly conversion/ upgrade but it might be worth it if you own an otherwise perfect condition camper.
