For now I have put a silicone sealant to prevent water from getting in. Thank you in advance for your responses.
First off, welcome to IRV2 and the Tiffin family!
Usually these stress cracks were in the corners of the slide cutouts. Most of these have been repaired by putting a trim piece over the crack then painting it to match. I would contact Don Boyd at Tiffin to see if they will help out with repairs. Send him photos of the area. firstname.lastname@example.org
