Rich,
That is both a kick ass Mod and a great documentation of the process.
Now you just have to make up a story or two to tell the right people about the charity work you do at the old folks home and how you go around and take some of the inmates...er...residents out on rides but some are incontinent....
Or maybe an ex-girlfriend that was into extremely large diameter..ahem... toys?

The possibilities are endless!
I remember you also said you were having a plug made, but I didn't see it in your video documentation.
The important thing is that your passenger is happy.
Could you show us some closeups of what you did to drill ventilation holes and how you keep the area watertight?
Thanks,
Dan
