All 3 of mine collect water. Looking at mine and others, it seems like the attachment could be an inch or so higher and prevent the problem, I don't know. I have overcome it with a device called "Air Wedge". Google them. I also use small beach balls or gallon milk jugs in a mesh bag on the br slide. I only put them out if I am staying somewhere for a couple of weeks.
The Jayco remedy is to run them in and back out.
If I ever replace the cover, I plan to investigate raising the slot brackets on the trailer wall an inch or so.
