Slide Topper - Help

Interesting to see this two years after I had what was a confounding issue. On an extended out of state trip my short bedroom slide would only push out halfway. I could not see anything unusual and the electrics appeared to be engaging properly as well. On top of that I had zinged and slightly bent my generator exhaust pipe on a concrete median on the Cross Bronx Expressway, so I was not the proverbial happy camper. Come to find out, when I had made contact with the anti-billow arm on a street sign next to my house coming home after my last trip, it had rotated such that it prevented the full rotation of the awning roller when the slide was actuated. Did not break anything but it was something I could not figure out without professional advice and assistance. Always something to learn.
