Hi Michael! Dana Lasswell here, of John and Dana. We are going to get the cracks in our roof repaired and they appear very similar in location and size to yours. Did your temporary reinforcement with rivets do the trick or did they end up requiring a weld at Sportsmobile? We're hoping to avoid a drive to Fresno and do have some really good welders in our area. A patch, adhesive, and riveting is well within our area of repair expertise if that appears to have worked for you. Any info you can share would be super. We spoke with Peter about it previously and just gave him a follow-up call as well. Thanks so much! Dana
