Thanks for the idea about placing the bathroom. With the handicapped toilet seat I picked up, I am hoping it will fit over the wheel well. If not, I'll move it elsewhere and think of something else.
Here's the bike I hoped to carry in the back at one time...
It's a 2006 Kawasaki 1600 Nomad - great touring bike! Unfortunately, between the large saddle bags and the aftermarket front faring, this puppy won't fit through the standard back door.
My first idea was to make the entire rear section of the bus into a fold-down ramp to get on and off, but that's an expense I'm not ready to take on yet.
My second idea was to add one of those material lifts that the cargo trucks use (like those on the back of an office-supply vehicle). I thought I could drive the bike onto the ramp, park it, then lift the ramp up to the normal floor level for travel. The benefit of this shorter ramp would be the ease of pulling in and out perpendicular to the bus instead of needing extra room to fold out a really long ramp. It would still leave the bike exposed to the elements, but the convenience would make it worth it.
My third idea is to just tow a "garage" trailer behind the bus. Not too crazy about that idea either, but at this point it's the best way to get all my stuff out west. In the mean time, I hope to pick up a Yamaha Zuma 125 scooter for commuting around the city. That will be easy to drive up the rear ramp the bus already has.
