Sourcing filon & roof corner/gutter - please help

Take plenty of pictures/videos of rehab to backup what you have done. Also helps to find wires in the walls down the road and other stuff.

I would plan on upgrading the power converter, they have better ones now that won't cook your batteries while charging.

As to worth, its worth whatever you can get someone to pay for it with the upgrades. I would say $10-$12k range based on what I have seen TC's listed at these days.
