I suspect, for a full size truck, not worth the effort.
You would likely experience more gain from lowering the vehicle, adding a front air dam and (perhaps) chopping the top. These would combine to reduce the frontal area and push air around rather than going underneath the vehicle.
That - and SLOW DOWN! The drag increases with the square of the velocity, so the increase is exponential, not linear.
