The Rockwell Commander 112 is a low-wing spam can with a "BOTH" position on 
the fuel valve.  I don't know how they make it work.  The only operational 
restriction on the "BOTH" position was set by the FBO, who requested that it 
not be parked in the "BOTH" position, since a slight tilt (or rocking due to 
the heavy local winds) could start fuel siphoning out of the overflow vent.  
Once that started, the fuel would crossfeed, thus enhancing the tilt, and all 
the fuel ended up on the ramp (or so they said).

In flight, the only position I ever used was "BOTH".  Seemed to work just 
fine.  I don't know what their secret is....
