I am thinking of mounting the road wheels on a frame and let the hull pivot. 
With the weight of the components evenly placed only limited force is needed 
to elevate the entire hull. When the frame pivots around a point halfway the 
distance between the idler wheel and the drive wheel (they will be mounted 
in the hull, not to the frame) the track length will not vary because of the 
elevation.
With an elevation needed between -10 and +12 degrees the hull elevation has 
to be minimal.
I am worried however about the fact that the elevation servo will be damaged 
by absorbing (or rather: not) the shocks when driving, especially when 
driving and elevating simultaneously.
So there's food for thought!
