Accumlating water on top of slide

[rvpacer]

4081 Newmar Dutch Star. Water is accumulating on top of the drivers side long slide. Then when you bring the slide in and leave, first time you stop you get a bath, all the water comes down on the driver.
Anyone have any ideas beside I use a towel on top of the slide when it's in.

I've had this occur only when getting the coach washed and someone (self?) sprays under the topper. If you know it was washed stand on your driver's seat and check the slide top to see if your bath awaits. If so, use your jacks to tilt the coach prior to retracting the slide the drain the water.

Usually when you drop the jacks the water comes off before bringing the slides in. If you see water draining just wait a bit before starting up and bringing the slides in.
