Has anyone ever hinged the arch in a 2006-2008 290 sundancer? On the trailer the boat is 13' 5". I want to put the boat in my storage building with a 12' door. I'm aware that I would need to have a stainless hinge made and a good fiberglass guy to reenforce the arah and repair. No one produces these hinges correct? Any advise on this subject would be appreciated.
