I was in Tucson about two weeks ago and noticed that an aluminum strip about 2" wide and 6' long was bulging in the middle. I noted that it is glued on. I observed that the temperature was over 100, and this piece exposed to the sun. I also noted that there was no space on either end for expansion. Conclusion, heat caused the metal to expand, but no were to expand to. Now when garaged in the shade, the bulge retracted. I am posting this to suggest that Gurus having this problem may want to trim the ends a bit to allow for expansion before putting the trim back on the coach.
