Wow, an endoscope. Fishing to a new level! For me, with my more mature rig, I've decided to do some preventive maintenance by replacing the rubber roof. After the old rubber is removed, I should be able to unscrew the edges of the plywood underlayment and slip a cable past the insulation and under the joints. If that becomes unfeasible, then back to all the great ideas collected in this thread. It's an adventure!
