We have a 2003 Minnie 24F, bought new in 2003. I have discovered several leak points over the years as follows.
In 2007 on a warm morning after a much cooler night I found condensation on the inside of the windows. Since the MH was stored in the driveway, this was a strong indication of a leak. After some searching around, I found that a long term leak had rotted the front portion of the cabover floor on the passenger side. The leak source was in the sidewall to floor joint where the metal trim strip that was supposed overlap and seal the sidewall had almost no overlap. When I pressed with my thumb on the sidewall just above the trim strip, the gap became obvious, as seen in the picture below.
I sealed the gap with a heavy bead of Dicor and check it often to make sure that flexing going down the road hasn't broken the seal.
A year or so ago I found that the driver's side sidewall to trim strip
showed separation when I pressed on the sidewall, so I applied a bead of Dicor to seal that as well.
I have also found that the front cabover window leaked, but not from the joint where the metal frame meets the front wall. The window is set into a U-shaped rubber that is in the metal frame. I found that the leak point was at the joint where the window glass meets the rubber. The water leaks around the glass and comes in from the rubber to glass seam.
Also had the center brake light leak into the rear wall. The brake light has a rubber gasket that barely sealed around the hole in the wall for the wires. Dicor fixed that.
Lastly, had a leak in the rear kitchen window. Sealed around the edges of the window, but I believe that the actual leak point was the butt joint in the metal frame. All of the other windows had sealant over this joint, but this one didn't. Sealed the butt joint and no further sign of a leak.
Check all the seams often, preventive maintenance is important!
