We first posted 2 yrs ago when we discovered delam & leaking on passenger side of 2003 Fleetwood Revolution ...due to health issue took it to Phoenix to store & dry out...after 10 hours of open heart surgery and 1 yr to recover, my husband was finally well enough to fix it this past summer.....turns out every rivet on the coach was leaking....even the ones that had silicone blobs on them, which looked okay. Once we popped the blob of slilicone off..the rivet fell out...most of them...plus the rivets were aluminum with a steel shank so as soon as water got in there they rusted off. Repaired by removing and replacing all rivets and properly sealing all seams....good to live full time in now...even in rainy BC this winter..after a bad start 2 yrs ago...finally enjoying rving!
