This is great information. Thank you for the reply, I appreciate it.I couldn't find a driver's side Pivot at all when purchasing, and I wanted to get it asap. The spare can swing into a wheel of the closest bike (when on a 1 up rack), though you can further tilt the 1 up down so that the spare hits the 1 up instead of bike (this also allows the gate to open a bit more). I believe you can also special order a reverse connection for the 1 up that sits lower and interferes less with the spare tire. There's another thread with some photos of a driver's side Pivot and discussion 1 up. The driver's side Pivot seems functionally better, though it apparently partially blocks the license plate. If you're fine with the partial blocking of the license plate, then the driver's side swing may be better. I haven't found the passenger side swing to be a big deal. I haven't tried combining the Pivot with any other racks than the 1 up.
