Welcome to JOF. I am assuming you are out of warranty. If the problem was identified before the end of warranty, I would get with a dealer, the same one that handled it before and see if they can get some relief from Jayco.
Are the cracks in the gelcoat or all the way thru the fiberglass? I had a similar problem with mine on the front cap, different place and it was repaired locally at a fiberglass shop under warranty. It was just in the gelcoat.
Keep us posted on the resolution.
