B+ motorhomes

Following BPlus' advice I used Eternabond on my major roof seams and it's true, seems like a bomb would have to take it off. It's not overly pretty, but it is up high and if you do a neat job, it won't look bad, and you only can see the front/rear edges from the street. It has a death grip once in place, for sure. I called there for additional advice when I received it and they were very helpful.
btw, hey BPlus, is the e that close to the t on the keyboard???:)
