Have had some issues with water leaks-contacted Winnebago in the past-was told 'Roof is guaranteed for 10 years' -Sealant isn't ! after many hours of chasing- there was a few on the sides & rear from sealant shrinkage as well as poor workmanship. Right front cap securing bolt when installed missed the metal frame- the sealant on that side pulled away causing a leak when torrential or windy. Hardest one to find was front cap draining onto Dash and inside front on top of Generator ! This also caused the A/C to quit working due to corrosion of the A/C temp switch. This was the 'Marker' Lights where they mount the fibreglass was 'dry' no epoxy or gelcoat-looked like a glass air filter View attachment 152 After sealing the marker lights-Dash has been dry-still have to reseal r/side cap and secure to frame.
