The aft sunpad on my 2008 Starcraft has a 29" offset piano hinge that attaches it to the frame. When you raise the pad up to access the engine and fuel tank, or trim the engine too high, the cushion binds against the next cushion forward. I'd like to change the hinge out with a new hinge that allows the sunpad to still flip up, but also to be easily removable when I need to service the batteries, fueltank or take off the cowl.
I'm imagining something along the lines of this

or this
but it needs to have an offset to replace the function of a hinge like this:
Anyone got any out of the box ideas how I can make this work better?
Thanks
