Here's an update. After getting the coach back and being assured it was sealed it leaked again. Water ran down the same spot over the drivers window and dripped on the dash. Exasperated I climbed up on the roof and aggressively poked and prodded every seal I could find. The seal for the skylight over the shower moved and water squirted out from underneath it when I pressed it down even though it looked fine and water had never dripped in the bathroom area. A call to Winnebago revealed that the seal was close to the edge and a rail runs down the entire length of both sides of the coach. Even though the shower skylight is towards the rear of the coach the water can run the rail up to front and drip on the dash. The dealer re-seated and resealed the skylight and Winnebago picked up the tab even though the coach is out of warranty (slightly). Hopefully, this will do it. I guess the lesson is that even though the seals look like new they may not have adhered to the roof properly in the first place.
