I have a leak in a weird location in the upper bunk of my class C, as evidenced by a damp area on the cushions. But I've never seen it leak as I keep it in a lot away from the house. Further, in my area rain is heavy but rare.
I suspected that it would have been from the front window of my 1993 Minnie Winnie but I know that the window was recently sealed, there is no visible evidence of a leak there (or anywhere) and the cushion is not wet near the window. It is wet away from the window, obviously getting wet from above.
There is a roof vent over the cushion, but the wet area does not appear to be directly below the vent, but about 6" away or more.
I'm at a loss. Ideas?
