the slide seals on my 23SS's slide stuck to the side of the trailer, for the first year, due to sap when camping in wooded areas. i actually had to use a butter knife to break the adhesion.
got a slidetopper after that first year and have never had sticky seals again.
did the slide stick for awhile before it opened up?
