I am new to this site and new to popups. (Sorry if I am doing this wrong or breaking post etiquette). Please let me know). I got a great deal on a 2005 Fleetwood Yuma because the PO did not have the time or energy to fix a leak around the AC. Other than this, the camper is in great shape. The floor is solid. Canvas barely has any staining from the leak. He took good care of it. I’ve been reading posts on here for a few days, and it sounds like this is a really common issue. I’ve read several strategies folks have used, and given that I’m pretty handy, I’m confident that I can get this lil buddy in tip top shape. Not, however, without some help from you more experienced popup repairers. From what is visible, it appears only the rear half of the ceiling is bad. Already have much of the luan pealing away. The front half of the ceiling appears to be in great shape. Again, that’s what is visible. When I press on the styrofoam in the back, bad half, there is no moisture. It’s been under a tarp for a while, so may have dried out. So I am unsure if I should do what so many recommend and take the top off. I’m not sure if I should remove all of the styrofoam on the bad half and check the aluminum shell, or if I should just pull the AC, check the aluminum around it, seal the area around it, and replace the gasket. Remove the rest of the luan from the styrofoam and add a new layer. As you can see in the pics, the typical sag from a too heavy AC unit is where the water got in. It needs more support, but if the styrofoam is still good, I’d hate to take it all out. Will I need to remove it all in order to create the necessary support? All of the threads I have read have been for full roof rebuilds. I’ve got a partial, I think, and I don’t want to create unnecessary work. But I also don’t want more damage and to have to do it again. What do you guys think? I am sharing some pics now, and I will document and share the entire process. The posts on here have been super helpful! Thanks!
