Thanks for posting this JM3972...sounds exactly like my leak...our stories are pretty much the same...except for having the unit in a shop to look for the leak (or leaks). I've worked at covering sections of the cabover during a rain, have most seams eternabonded and have caulked the cabover windows (no front window). From your description the water is showing in the cabover in exactly the same spots. Shortly after purchase (December 2011), and after a humongous rain, there was so much water in the front part of the cabover I had to remove the foam...I've kept it removed and it has made it much easier to check for water after a rain. I keep the motorhome level so I don't believe the water is travelling from the back part of the unit. BUT, I don't know where it is coming from...and really don't have a clue. I've continued to enjoy Winnie...just wish I could solve this. Your thread may shed some light.
