I know this post is from April, but now that we are going into the Fall and Winter months many people will begin working on their Trailmanor for next year. I had the very same problem as Randy. I spent well over $100.00 on the "wondertape" and it still did not solve the problem. I ended up cutting the tape off the corners of all the vents and just sealing them with with what seemed like a ton of the 3M 4000 sealant. It isn't pretty, but it did the job and stopped the leak.

I have decided my next project will be to cover the entire roof with Dicor Elastomeric RV Roof Coating. I have read on other sites that many people have used it with great success. I also ran into a TM owner not long ago that said he used it and never had a leak. I am going to lightly sand the room, trim down the 3M 4000 caulk and paint it on the entire roof and up and over the shrouds for the A/C and vents. My thought is that the elastomeric coating will fill in the small cracks. I have also heard it is best to do two coats.

If anyone has done this already, I'd like to hear your results.
