We were out for our 11th and 12th nights of the season (and for this new unit) on the weekend - five trips - the slides have probably been opened and closed at least a dozen times, all with absolutely no problem.
Opened the slides on Friday afternoon, and I heard a loud crack - stopped the slides, checked and did not see anything - proceed to open the slides fully and then inspect - problem is the left rear bedroom slide - the fascia the closest to the back of the unit, including the framing piece, has popped out, popping all of the nails in so doing - it looked as if the framing and fascia was too long!!!
I was able to pop it back in to place and when I went to close the slides, it closed without any difficulty or any other cracks or noises - I then re-opened the slides and closed them when I got the unit back to our storage location, without any problem!
Anybody ever seen this before - could it have been expansion caused by humidity? Just eyeballing the slide, there are no readily apparent defects, inside or outside the unit, and like I said, it worked at least a dozen times before, and has now worked again after the issue...
