If you need better efficiency while driving, you can most definitely improve on the efficiency or amp draw of any RV roof air. Not a whole lot you can do when parked.

Correct the roof AC's are not at all efficient, compared to what is available for residential. There are limits, since they must run on 120 volts. If efficiency was to be increased meaningfully they would have to run on 220 volts, which is not available from any of the pedestals that I know of in any RV park I have been to.
