I removed Sunbrella panel of dinette slide-out side on our 2010 Coleman Utah Roof back in Fall 2017. At the time, pulling out the rubber gasket/gusset at top of panel from aluminum track required some force. It might be that pulled too hard and now the aluminum track is unattached ("blow out" on the 12 screw/rivet/widget anchors). Fast forward to now and just had a look. Did bit of cutting and opening up and the wood looks to not have its original integrity (four pics attached). Thinking water got in there. This previous post seems to cover the issue quite well: http://www.popupportal.com/threads/roof-rot-up-under-the-roof.92146/#post-925110 And these other posters covered the topic: http://www.popupexplorer.com/forum/index.php?topic=89276.0 http://www.popupportal.com/threads/fleetwood-avalon.76452/#post-704373 This post might be way or procrastinating to dive into this repair...however wondering if any other folks have had this issue and any additional tips on the repair? Cheers!
