If you're in gear, it will do both, and have the potential to capture a lot more energy from two wheels with the vehicles weight on them than from a 5th wheel arrangement.
You could possibly run a two stage system one that operates at neutral/idle, and a higher rate during over run/braking.
In a RWD, it would be fairly easy to add a compressor to the axle housing/ driveshaft.
I'd like to know how much energy is lost from compressing air to then reusing it. My daily is a FWD but there was a AWD option, so fitting the rear drive system off a AWD and adding a small motor to drive it all would be pretty simple.
