Mystery window leak

I have a í12 Itasca Suncruiser 35P. The (inside) gutters of the 2 windows above and next to the driver side door fill up with water every time it rains. There are no weeping holes in these windows.

This makes it strange:

There is no condensation. The windows are completely dry. Iíve taped Kleenex in the middle of the windows to see if it would collect any moisture. It stays completely dry, but the gutter fills up.

Iíve checked the outside window caulking, which looks fine. Just to be sure, I put tape over the caulking to make sure no water enters that way. Didnít make any difference.

The walls around the windows are dry. No sign of any dampness/moisture.

We have to wait another week before the floor in our new motorhome garage is strong enough to store it inside. Unfortunately, the weather forecast says it will rain every day this weekÖ.

Any suggestions?

The water is entering through the trough the one sliding window tracks in. The frame may be slopped down hill from the inside out; therefore not needing weep holes.

Gutters on our previous MH dripped on both driver's and passenger window. As it sat, front end lower than rear, water ran from slider half of track to fixed half and filled up the inside track.

I think that is what RV Wizard is describing as well.

my 99 winne chieftain has the same window and they leak too. I have a piece of tape on the window and a large bowl on the dash where your water puddle is in the photo.

If you don't collect the water it could end up below your dash on the speed control module for the wiper motor. I know.

I have tried everything for three years to eliminate this leak. Winnebago just sucks at design. my fiberglass roof used to leak inside at the gutter. water would accumulate in the extrusion and when we slowed down to a stop,we would end up with this reservoir of water running forward in the channel and ending up on the dash area on either side once spilling on to our lap top..

just had to replace both my windshields because they cracked. The glass company said they crack because of rust on the pinch well causing pressure on the glass. the right windshield crack in the lower right corner and the left windshield crack up the middle from the bottom from the metal tab which holds the window elevation rusted.
