Hi there,
Did you ever get any answers on this and did the dealer repair the rdome to your satisfaction?
I also have an issue with our rdome. I just bought a 2015 179 used from a private party and one thing that made it a good deal for us was that it came with the lift kit, door window, cover, and the rdome. We just set up the rdome for the first time and the zipper on the front cover had been split and the previous owner had stitched the top part together. I would like to have it open all the way so would like to get this repaired. Is it worth it to try to send it to dometic or is it better to find a tent and awning repair and see if I can get it done?
