Just wanted to update this. I recently got this:

so I don't need the extension for the North Shore rack.
However, I'd still like a way to carry the bike when towing the trailer (hauling a Jeep). So I decided to try to hang off the ladder.
I can't use a standard ladder rack due to my seat tube and suspension configuration. So I had some cut-off waste from shortening factory Yakima bars (coated 1 1/8 tubing). I attached the bars to the ladder with some quality hose clamps.


However, with the bike hanging this way, it creates a little more leverage to allow the ladder to flex side to side. So in true Griswald fashion, I attached a ratchet strap to complete the custom look. Now it's solid I'm not worrtied about it.
