I would use skid-steering on the rear tracks and let the forward wheels 
turn freely.  The tracks should have no problem turning the vehicle as 
long as the front wheels are free to rotate.  If the front wheels swing 
back and forth too much when moving forward, a couple springs will solve 
the problem, while still allowing them to rotate when turning.

The Goer (SV005) uses a similar, but reversed, set-up, where the front 
drive wheels steer the vehicle and the trailer just follows it through 
the turn.  A couple springs snap the trailer back into alignment when 
the turn is done.
