Newbie with a slide issue. I have a 97 Wildwood 5th wheel, just recently purchased. Brought it home, did some cleaning, winterizing, yada yada. Went to close up the slider, and one end seems to catch the carpet, and not retract, Any ideas as to why this is happening? I even tried to bring it in with the hand pump to no avail.

Slide worked fine when I bought the trailer, checked both in and out operation, and went out fine when I got it home. Now one end will start to retract, and not the other. Any help will be greatly appreciated.
