Many excellent comments here! I have a 2000 Winnebago Minnie Winnie DL and have "managed" a cabover leak since purchase in December 2011. My shortlist when looking to purchase my Class C was to have a cabover that had nothing in it so that if I had a leak it would be easy to spot and not have to pull out a lot of stuff. Weeks after purchase I had a water soaked cabover. I removed the front part of the foam, dried and put a foam piece in that could easily be removed. I've managed that area for 3 years and have now Eternabonded the seams that the OP is speaking about. I had earlier Eternabonded the roof seams. If I had it to do over I would have Eternabonded everything and not dealt with Dicor (or similar) sealer. In the meantime we have traveled 23 states and over 20,000 miles and have more planned. I continue to get my moneys' worth from the purchase. What a DANCE!!!!!
