Oddly enough I was wondering the same thing. I am putting an '04 T800 up for sale and thought it might make a good expeditor. It has an 86" sleeper and a 260" wheel base . It measures over 14' from the sleeper to the end of the frame.

It currently has a drom cabinet and deck behind the sleeper where we keep our motor scooter.
http://home.comcast.net/~jroddick/0.jpg The back of the sleeper is completely clean, no grab bars, lights, fairings, etc.
The truck has approximately 220,000 miles and looks like new.
