Well... Unfortunately I have to agree a bit with meangreen. If you're going to have a passenger for more than 100 - 200 mile jaunts, I don't think you can do anything to the Meanie to make it comfy for the passenger. I'm lucky (?) that my wife doesn't like longer rides, and for daily runs with her on the back the Mustang does a good enough job.
Just another reason to have an additional horse in the stable...
