But this wouldn't be considered a good bonded ground. I realize there
is lots of downward force on it, but technically there is no good
electrical connection.
I had marked this thread to follow, since I'm in the same boat. I'm
wondering if a separate ground line strapping the top of each section
together (top so that it can still be lowered) is needed.
