Hmmmmmmmmmm. I learned something today. I re-caulked my roof soon after we bought it as the old caulk was deteriorating, and I was afraid water leaks could result. I used a high quality, outdoor Silicon product. I'll have to check it a little closer this spring knowing this possible problem.
Actually, if you look closely at the drawings that have been posted earlier, you should note that it would be almost impossible for water to work its way around the channel. The caulk is what holds the roof in the channel and has little to do with keeping water out of your coach.
