When I winterized my 5th wheel ie. washing and waxing, I noticed at the top along the edge next to the gutter, in the front panel ,a small crack. Given the height the crack it was not noticed from the ground.(the unit is stored inside during winter) I don't know if it was stress related or during my travels this summer a rock or something caused the crack to appear. I am concerned about the crack getting larger and having bigger problems if not repaired. Question: How should I repair it and should it be repaired before cold weather sets in. I am looking for a permanent solution. Any adivce would be helpful.
