Wow, a timely thread for me. Last week while parked in front of the sign at the Wakima, WA Elks I pulled forward and the rear slide topper bracket caught the sign. I was not quite so lucky. Because I was turning away from the sign, the spring mechanism raked along the rear portion of the gutter, bent it severely as I pulled forward, and deposited the mechanism on top of the hood of my F150 toad. OUCH!!
Due to a lack of resources and the bent/damaged gutter, I went ahead and cut the fabric to release the rest of slide topper. I just used the link from Grumpy's post to contact Jayco for a replacement topper. I hope I get a good response so I can get the rig repaired soon.
I might have a few reusable parts left in the pole barn after replacement should a need arise in the community.
