I noticed Maggie kept hunting with her back leg for a step, so I thought this would do the trick. It's from a Honda Pacific Coast (PC800) motorcycle. Good theory and matched the motorcycle theme, but in practice she would just jump clear into the trailer with this in her way. I spent a lot of time chiseling into the 2x6 so this would be level and flush. All a wasted effort, but it was a good thought.
