Decided to take a look on top of slide while retracted. Wow, it's been a year or so since I cleaned it off and was amazed at how many pine needles etc. had accumulated behind the inside seal. I remember last couple of times camping we were under pine trees and the needles have a way of going under the seals.
Thought I would mention it in case some of you have some time on your hands are looking for something to do on your coach.
I would have taken some pics, but it was to ugly.
