I have a 2016 Sierra 355re with 5 slides. The problem I am having is the bathroom slide leaks water in the rear corner when it rains. When we bring the slide in or out we hold the switch in position for 5 seconds. I have brought the slide in and checked the top of it and it looked ok. When the slide is out all the wipers are out and they look good. I had an r v tech plus 3 other people look at it but they couldn`t find the leak. I need HELP.
Thanks for the reply Sea Dog. I think I found the problem with the slide in question, it has the Schwintek slide system. What I think is happening is the water is running down the rails to the inside of the trailer because the trailer is a little bit high on that side.
