Howdy, I have a 2003 Winnebago Mini 24V. Just quick comment/recommendation for the corners where the wall meets the horizontal surface in the over cab. I have removed all the aluminum trim and calulked the joints with Proflex, then covered the corners with Eternabond (cut the long way to appropriate width) then replaced the aluminum trim with stainless steel screws. It has held up well for 3+ years. It was a great deal of work but the dam thing would have rotted out without doing it. I learned everything I know about this vehicle from Clouddriver. (member of this forum) He is extremely knowledgable.
